Hi U.H., Thank you for making another clear, concise video. Nice job! You are helping build my confidence to try projects that I never thought I'd ever even attempt on my own. I look forward to learning more from your channel. Sincerely, Caroline in Connecticut
One tip I'd add... use a drill, not an impact driver. I find that an impact either over-tightens or otherwise somehow weakens the thread cut into the concrete, and you often end up with the hole being stripped out and useless. A drill works much better
Or it's the case where you don't know what you're doing with an impact driver. I've installed loads of these masonry screws over the years with an impact and have had no issues. You stick with your drill 😘
@@tomalex4806you install for other people who are not paying attention, despite your installation not being optimized. You did a fast job, but your customers don’t know not the best way. As the video says, the masonry screw is being threaded into the Pilot hole in low even pressure, but pushed in by an impact driver.
you have just saved my life as I need to screw down a wooden archway into paving and was wondering what to,ie buy some type of raw plug but this seems a lot easier.
Perfect! I've had some slabs laid outside of my permanently sited caravan for my full awning to go onto, And these will be Ideal in place of the tent pegs. I'm ordering some M8 plastic wing nuts for the awning rubbers to go over, And screw em down. Excellent solution. Thank you! Rob J.
Thanks Sir, i was looking for how to instal a ceiling fan without the electrical box that is used to put the bulb. I dont have this little and metal box. So i will install this ceiling fan with this concrete screws! Hugs from Dominican Republic
I don't seem to be able to find out what size / how much smaller a drill bit to use to drill a hole for e.g. 7.5mm concrete frame screw (AKA tapcon)? I could do with a 4.5-6mm drill bit but it's just my guessing and am sure therre is an optimal hole size so it doesn't get stuck in while screwing in or become too loose and risk loosing grip.
Yeah, I'm looking for to know what would be the correct size, as I'm not sure if it's the same size of the screw... You could have said what is the "correct size"!!!!
There is no simple answer to this, which is why I didn’t specify a drill size in the video. It depends on the manufacturer, which is why they normally specify which drill size is required. If you don’t have the manufacturers instructions, I would suggest drilling holes in a scrap piece of material, to ensure you get the correct diameter hole. If the hole is too small, you can crack the substrate, if the hole is too large the fixing will not hold correctly!
I want to mount a fingerboard on plywood to a brick wall. I bought masonry screws with rawl plugs, and understand I need to drill a hole in the wall before screwing/hammering it into place. Do I use the drill on the plywood and then on the wall? What's the best way to ensure the plywood holes line up with the wall holes? Thanks
Yes, just spot through the plywood. Drill one hole through the plywood, then into the masonry. Put the wall plug into the hole and screw it into position, get it level/plumb and then spot through the other holes 👍 Example here using a TV bracket, the only difference is that you have to drill the holes in the plywood- ua-cam.com/video/FlDuaAMiSxw/v-deo.html&t
It depends on which screw you are using. It normally tells you on the packet. If you do not have that information, I would recommend testing them out on a old brick or piece of masonry. If the hole is too small, the screw can crack the masonry. If the hole is too large, the screw will not hold correctly. Thanks for the comment 👍
It depends on the screws. There are so many different makes and sizes, you just need to drill the correct size hole for the ones that you are using, this is normally printed on the packaging.
Yes. The packaging will say the pilot hole size, typically 1 size smaller in drill bit size. In the US, a 1/4” screw would suggest a 3/16 Pilot hole for concrete screw. For larger diameter screws, the Pilot hole may be the same size, but read the package. In case the Pilot hole is too large for the screw, you can fix it by wrapping the screw thread with a thin metal wire . See UA-cam for this fix. And if this doesn’t sense to you, then don’t attempt to use concrete screws.
Hi, I'm trying to lay a floor using scaffolding boards. The floor underneath is concrete. Would using these type of screws be suitable to fix the boards onto the concrete? Also, I see that in a previous comment to Rodger Waldram you have said the screw part sticks out a but. Could this be resolved by counter sinking the screw heads? I don't want to be stubbing my toes on them! Any advice would be gratefully received! Thanks. Anna
Yes, you could use these to fix scaffold boards to concrete. They now make a huge variety of these so as long as you get countersunk ones there should be nothing sticking up above the surface.
Hi I'm wanting to mount a hangboard (for rock climbing training) above a door way into brick. I'm a complete idiot when it comes to DIY, the instructions say use 4 masonry screws and rawl plugs. Can you explain what this means?M10 x 100 x 5 (this is on a pack of 4 screws) would it be suitable? Thanks for your time
M10 is probably the size of the hexagon head on the screw (it will need a M10 spanner or socket) 100 is the length of the screw (100mm, approximately 4 inches) 5 will be the diameter of the screw. I'd use wall plugs to be honest, rather than masonry screws- ua-cam.com/video/V4wVyyfbWog/v-deo.html&t
Hi there, great video. I'm looking at buying a few concrete posts to put some heavy duty fencing up. I want to attach a 4" x 3" timber to the concrete posts and hang a gate off. Questions: 1. Would these concrete screws be OK to go through timber AND concrete? 2. Assume pre-drill the concrete but NOT the timber batten? Thank you!
I have used these for a similar thing, but you need to drill a clearance hole through the timber. Then drill through with the pilot drill into the concrete. Once the concrete screw starts cutting a thread in the concrete it will pull the timber really tight against the post.
You are welcome The hole diameter is normally on the box and is a critical size, but if you don't know that, I would get a drill bit slightly larger than the diameter of the shank. Thanks for the comment 👍
@@Gibonz The widest part of the screw is normally the threads, not the shank. That's why you need a drill bit larger than the diameter of the shank, otherwise the screw will crack the brick/concrete when the screw is driven in.
Great vid! do you have to drill a pilot hole first? or do you know of anything that will drill into brick without pilot holes? I remember working with a glazier a while back now who had some fixings which did this, all best
Yes, you have to drill the exact size pilot hole for these to work. I do not know of anything that you can screw into brick without a pilot hole. The glazier was not screwing into thermalite (aerated concrete) was he- you can drive normal wood screws into that, with no pilot hole. Thanks for the comment
I’m not sure what the advantage is. If you’ve filled a hole then the only thing you don’t have to do is put the plug in. It doesn’t really save time does it?
Wall plugs work on expansion, so they cannot be used close to the edge of a brick for example, as the expansion will crack the brick. These are also good if there is a fire, as the plastic plug will not melt (say you were fixing something to a concrete ceiling) Also, you don’t need to drill the larger hole, which is required for a wall plug 👍
I started to drill a pilot hole in my house cement foundation using a regular drill and a masonry drill bit. However, I now find that I'm not making much progress after 20 minutes. If I decide to use a hammer drill to complete the pilot hole, will I need to change to a hammer drill bit? Thanks.
Ive a seen these used for decking ledger on brick. How do they compare to expanding bolts. With brick being more brittle could they and come loose with small movements a deck would have?
I normally use thru-bolts for decking ledgers, as it's easier to space the ledger away from the property using washers. I'd use the thru-bolts to be honest. Thanks for the comment 👍
It's better if you can see what you are fixing into, with a plastered wall, you cannot see the bricks behind, so you could be drilling into the hollow part of the brick (depending on the type of brick). Normally as a general rule of thumb, I only use these if I'm fixing something where it is difficult to remove the item in order to insert a wall plug. For example I once fixed a sheet of insulated plasterboard over a plastered wall, so I just drilled straight through and used these to hold the sheet in position 👍
The hole needs to be deep enough so that the screw won't hit the bottom of the hole. I can't remember what size the screw was now was it was filmed a few years ago, sorry. Thanks for the comment
Love your helpful videos. Always been concerned that if I use these they could create cracks near the hole. Would it? I have concrete basement walls and a new crack would make water problems for me.
Hey, I just watched a video on another channel about using brick veneer on an interior wall. I really like the look and would like to do something like that in my dining room. My question is is the brick veneer gonna be solid enough to still hang pictures on? Would I need to use masonry screws to get through the veneer and into the stud?
You could, but depending on the height of the balustrade from the floor, you might need a structural engineer to do the calculations and specify the correct fixing (obviously if there is a drop and the fixings fail, you do not want someone getting injured) Thanks for the comment 👍
Hi, Ive drilled into my house wall outside ..Not sure the width it takes black rawl plugs.I tried using old bed screws to fix 4x3 wood for a gate frame,but they really won't screw in,I think the thread is too small or they are slightly too wide. Do I buy masonry screws anyway, even with rawl plugs in? and Ive got to say...thanks for vids, Ive subscribed and FINALLY I can do some decent DIY :)
I have a concrete garage, at the moment I have a gate post attached to it, will this hold please?, would these screws be ideal or would bolts work better?
@@ultimatehandyman I need a cordless SDS to drill a few holes into an old concrete garage floor. Will a cheap £80 cordless Bauker brand SDS drill be suitable?
What size of pilot hole did you drill and what size of screw did you use? Does the pilot hole need to be a mm narrower for a tight fit or does it the same to be the same size? Thanks.
I can't remember what size I drilled the holes, but the hole needs to be quite specific. It should say on the packaging, telling you which diameter drill bit to use. If the hole is too small the screw can crack the substrate and if the hole is too large the screw won't grip. Thanks for the comment 👍
Great video, would you use masonry screws to attach a wood batten to a concrete fence post using the holes in the post? I would then hang a garden gate on the wood. Thanks
Sorry another question if I use four of those screw will they hold a fan that weights 6kg .. plus the company said cos of the down pressure I should times that but 10 so the total weight when the fan is on will be 60 kg of is this correct or four of these? Will be more than enough to hold the fan up. Thanks
Not sure, but for light fixings I normally just drive a wood screw directly into aerated concrete without drilling a pilot hole. For heavier things I use these- ua-cam.com/video/YwAMQcbJS0U/v-deo.html
Very informative cheers. One question though what would I use to secure a Suspension trainer anchor to a single skin brick wall in my garage. It will need to support my weight - about 17st thanks in advance
I'm going to use these to secure hardibacker to the bathroom walls, do I need to drill a small pilot hole 1st as when I try to put these straight in like you do in the video it either hits the wall behind the board n just spins and when going through the board it's a struggle to keep it straight and ends up going in at n angle . thank you. just watched again and noticed the small pilot hole lol
thanks pal , had a go and out of 10 screws that went in 8 pull straight back out , the wall is breeze block so it's my own fault gonna take the boards back off and use flexible floor tile adhesive as recommended by the manufacturer. wish I'd have known this when I started but oh well lesson learnt.
Better in 2024 with the arrival of impact drivers :) Almost spun me around the drill a few times these back in the day when I was using a combi or even mains drill.
An impact driver works worse because the way the impact works and drives screws, well impacts them, it cracks up the concrete inside the hole and makes the thread weaker. Use a drill with a handle
I am going to attach some fence posts to my garden wall (brick) I am thinking this will do the job without having to worry about wall plugs. Are they just sold as concrete/masonry screws or is there a specific name I need to ask for. many thanks for the vid ;)
Yes, they are just sold as Masonry/concrete screws although there are several trade names such as Multi-fix, Dewalt Tapper, Tapcon screws ETC. Thanks for the comment
Somebody fitted my rainwater system downpipe using these screws straight into the (soft) brickwork. One of them has pulled out, so I need to move and refit the 2 screws holding the bracket. I have no idea who the manufacturer of the screws is. They are 95mm long (seems excessive to hold plastic, but hey). So I don't have info on the correct size pilot hole to drill. In wood I'd normally match the drill bit to the width of the shank, under the threads, leaving the screw to cut its own thread. Would you say this would work for brick? Or should I drill a slightly smaller hole to allow to compress the inside edge of the hole?
It's best to test on a scrap piece of masonry first. I think normally you need a drill bit that is 0.5 - 1.0mm smaller diameter than the screw. The important thing is the depth, if you don't drill the hole deep enough you can crack the masonry.
It depends on the screws. There are so many different makes and sizes, you just need to drill the correct size hole for the ones that you are using, this is normally printed on the packaging. Thanks for the comment 👍
Hi, I do feel stupid writing these questions, however as mentioned before, I am a total newbie, and learning as I go. I have some of these types of screws, in the size of 7.5 x 60mm. What size hole would you do with your drill, to fit this size in, 7mm? which leaves .5mm of thread to cut in or would you use a different size hole?
I always drill the hole specified with the fixings as the correct sized hole is critical. Too small and you can crack the concrete, too large and the screw will pull out easily. Thanks for the comment
Unfortunately, these were bought off ebay, and there is no size on the box, for the hole you need to drill. Guess I will have to play around a bit with it.
I've just looked on Screwfix and the general consensus is a 6mm pilot drill. for a 7.5 diameter screw. Screwfix support is a bit crap on this item, they are saying you don't need a pilot hole LOL www.screwfix.com/p/easydrive-countersunk-concrete-screws-7-5-x-100mm-100-pack/3839h
Thanks for helping. When learning about how to work, it can be a nightmare. So many things to consider, if.....if you intend doing a good job. Appreciate your help as ever.
It would be a pretty weak solution. What you have to consider is your exposure to the weather and earthquakes. A light wooden structure can be lifted off the round and so you'll see some pretty fat bolts holding some things down. Proper foundation 'anchor bolts' come in a few different shapes - L , J or T (upside down). So the hooks/barbs are cast in the concreting process, and so stop the bolt from being able to ripped out. Masonry screws by comparison are only held in my the thin thread they cut - to pull out a foundation anchor, you'd have to destroy or lift the foundation. (also important to secure them to more than just the top row of blocks / masonry if the foundation is on a wall - for which you could use heavy duty restraint straps or longer anchor bolts.
@Ultimate Handyman, Another great video. Just one question: Does a concrete screw provide a stronger fixing than using wall plugs? Are there any downsides to using concrete screws rather than wall plugs? Thanks
Concrete screws can be better in some circumstances, especially in solid substrates, as there is no expansion force. This means they can be used for close to the edge fixing, where plugs cannot be used or the substrate can crack. I would imagine they will give a stronger fixing, as they cut a thread into the substrate.
Great video, what is the bit holder you’ve got in the drill looks good! I tried to do this and the bit didn’t hold up in bent then cracked off any tips?
@@ultimatehandyman After spending years using rubbish quality tools, Wera are like using alien technology. They are so strong. They can be ridiculously expensive but they sell sets of bits for really competitive prices.
Couple of questions if i may,i need to lay 6 inch deep concrete base 20 feet x 12 feet,worried about frost,,can i cover with dp sheet?,also do i need to put control joint in,thank you
I've laid similar sized concrete bases without a control joint. Frost can be a real problem, I'm not sure if covering it will help much. I have heard of people using a sheet and then adding some straw, but personally, I would only pour it when there was no frost forecast for a good few days. Thanks for the comment 👍
Hi might sound a bit thick but my dad always did my diy and he is no longer here I'm wanting to put some shelfs in my kitchen but my walls crumble it's a old build and I can't even hammer a nail in the wall without it bending Will these screws you are using work for my walls
It depends. If you can hit the end of the brick, or where the brick is solid, they work really well. But if you hit one of the holes, they do not work as well. I've used them with success on perforated bricks, you just have to be careful where you choose to fix. Thanks for the comment 👍
I've got masonry screws and drilled the holes into the concrete floor but the holes are slightly too big for the screws . How do I correct this slight problem?
Sorry if u have already answered this but I want to use torx masonary screws to fasten studs to concrete. Do I need to just dril a 6mm deep start off whole into concrete then drill the screw in and it cuts itself a thread or do i need to drill a whole deeper than length of screw, so a 80mm screw would need a 90mm whole ?
You need to drill a hole of the exact diameter specified by the screw manufacturers. The hole needs to be slightly deeper than the length of the screw, because if the screw hits the bottom of the hole it can crack the concrete.
I'm attaching a garden gate post Pedestal to a concrete slab. Assuming there is only loose sand/dirt/rubble under the slab, would you use concrete screws or masonry anchors with the chance the slab is a couple of inches of concrete then worm habitat beyond ? Appreciate your vids :-)
Vincent Palmer Thanks ;-) I think the concrete anchors would probably be best, they will expand and should hold the pedestal once they are tightened down.
Excellent videos thanks. Do you think that this would work in decent sandstone walling? To what depth? 100mm +? What about rather decomposed/damp sandstone?! (Some stones are better than others). The reason is to retain some wooden roof timber to prevent potential roof movement. Perhaps there is an alternative such as Rapier Starfix or Hammer-In? Thanks for any quick thoughts!
Thanks, these should work to be honest as long as you use long ones like you say 100mm into the sandstone. I have used them in sandstone in my last terraced house and they worked fine. Another option might be resin fixings? ua-cam.com/video/oUJPjJsdl0c/v-deo.html
Thank you greatly. Perhaps also, the resins will bleed deeper into the slightly decomposed sandstone and help strengthen the immediate area around the fixing screw/bolt.
I just came to my mind "why they dont even make a screws for concrete without the need of tox or expansion bolts" but here we are, there it is courtesy of youtube 😁
I used these a few days back when fitting a kitchen, I hung all the wall cabinets, but needed a screw to go through the back of the cabinet and into a concrete block wall. These worked perfectly 👍
Yes, these will screw into breeze blocks as long as the correct diameter hole is drilled first. Obviously they will not be as strong as using them in solid concrete/blocks etc. Thanks for the comment
These will work fine, but they will not be as strong if you get the hole in the hollow part of the block, as the walls of the block are not very thick. Thanks for the comment 👍
It depends how much weight you want to fix to them. They are okay in some situations on breeze blocks, but they won't hold too well if they go in the hollow bit- but you could use snap toggles if you hit a hollow part- ua-cam.com/video/tAIUublenMw/v-deo.html
+Roger Waldram I'd use screws and wall plugs to be honest. These fixings are no good for battens as the screw part sticks through the top of what you are fixing. You need a flush fixing for battens, so good quality countersunk screws and wall plugs will work best ;-) Thanks for the comment
+Ultimate Handyman Thanks. Never been a d-i-y'er in UK, but since 'retiring' here to France I am doing it myself & enjoying it! These UA-cam videos are a godsend. Thanks again.
Can you tell me if they would be correct for fixing moisture resistant plasterboard to a brick wall that has plaster on it? I have put up 'hardie backer board' with adhesive but I think both it and the plasterboard would need something like this?
Are you sure that you can install hardie backer boards using adhesive? Someone asked me about fixing aquapanel using adhesive a few years back and so I asked the manufacturers, who said that you should not use adhesive- www.ultimatehandyman.co.uk/forum1/dot-dab-aquapanel-direct-bond-aquapanel-t3056.html
It’s not that easy to drill these in like the video ! I been trying to and can’t , even after I used a drill beat. Still couldn’t get it through my pavers
animal79thecat You should be able to. I have even used them in bricks before now. As long as the drill the correct diameter hole and ensure it's deep enough they should be fine ;-)
Concrete screws/masonry screws have a much wider thread than a wood screw and are blunt at the end (they don't have a point like a wood screw) Thanks for the comment

I started to drill a pilot hole in my house cement foundation using a regular drill and a masonry drill bit. However, I now find that I'm not making much progress after 20 minutes. If I decide to use a hammer drill to complete the pilot hole, will I need to change to a hammer drill bit? Thanks.
Yes, a masonry drill bit is essential 👍
Ive a seen these used for decking ledger on brick. How do they compare to expanding bolts. With brick being more brittle could they and come loose with small movements a deck would have?
I normally use thru-bolts for decking ledgers, as it's easier to space the ledger away from the property using washers. I'd use the thru-bolts to be honest.
Thanks for the comment 👍
Would it be easier to use an impact driver or wrench to screw in the screw? Or will it crack the concrete?
Yes, a impact driver should work great with these. When I made this video, I did not own a impact driver ;-)
Thanks for the comment
Any disadvantage compared to normal plugs and screws when used inside the house, say mounting a cabinet to a plaster wall? Cheers.
It's better if you can see what you are fixing into, with a plastered wall, you cannot see the bricks behind, so you could be drilling into the hollow part of the brick (depending on the type of brick).
Normally as a general rule of thumb, I only use these if I'm fixing something where it is difficult to remove the item in order to insert a wall plug. For example I once fixed a sheet of insulated plasterboard over a plastered wall, so I just drilled straight through and used these to hold the sheet in position 👍
@@ultimatehandyman Thanks pal, your vids are brill.
Good (and unambiguous) as ever video! How deep did you drill the hole? And what size was the screw? Thank you.
The hole needs to be deep enough so that the screw won't hit the bottom of the hole.
I can't remember what size the screw was now was it was filmed a few years ago, sorry.
Thanks for the comment
Love your helpful videos.
Always been concerned that if I use these they could create cracks near the hole. Would it? I have concrete basement walls and a new crack would make water problems for me.
You need a hammer drill for that or would a normal drill do?
You normally need a hammer drill to drill the pilot hole.
Any drill/driver/impact will drive in the screws 👍
Wow nice
Thanks 👍
Hey, I just watched a video on another channel about using brick veneer on an interior wall. I really like the look and would like to do something like that in my dining room. My question is is the brick veneer gonna be solid enough to still hang pictures on? Would I need to use masonry screws to get through the veneer and into the stud?
Thank you just what I was looking for .
You are welcome
Thanks for the comment
and you can screw these into a brick without use of wall plugs (rawlplugs) anchors etc ? if so great nice video
Yes, you just need to drill the correct size pilot hole and you can drive these right into the masonry.
Hi can you use these to fix posts to patio flags for a glass balustrade
You could, but depending on the height of the balustrade from the floor, you might need a structural engineer to do the calculations and specify the correct fixing (obviously if there is a drop and the fixings fail, you do not want someone getting injured)

Hi, Ive drilled into my house wall outside ..Not sure the width it takes black rawl plugs.I tried using old bed screws to fix 4x3 wood for a gate frame,but they really won't screw in,I think the thread is too small or they are slightly too wide. Do I buy masonry screws anyway, even with rawl plugs in? and Ive got to say...thanks for vids, Ive subscribed and FINALLY I can do some decent DIY :)
I have a concrete garage, at the moment I have a gate post attached to it, will this hold please?, would these screws be ideal or would bolts work better?
What drill are you using I thought a normal combi drill can't drill through concrete and you need an SDS drill?
A combi drill will drill through most masonry, but SDS drills are much better at doing it, especially on hard concretes or tough bricks 👍
@@ultimatehandyman I need a cordless SDS to drill a few holes into an old concrete garage floor. Will a cheap £80 cordless Bauker brand SDS drill be suitable?
@@tommyharris5817 Yes, that should be fine. It will probably last you a few years depending on how much you use it.
@@ultimatehandyman Thanks
@Ultimate Handyman Could you pls. tell the sizes of these screws, those look terrific 🤔😲
They come in various sixes- bit.ly/303tPVI
@@ultimatehandyman Thank you so much, I am a week-end warrior and this is essential to my #stayhome projects 😃
@@SilhSe You are welcome ;-)
Great video & thanks for sharing 👍 Would you recommend these for fixing timber batons to existing concrete fencing posts? Thanks 😊
Yes, they will be fine for that. I have used them for similar jobs in the past ;-)
Thanks for the comment 👍
DOES IT TELL YOU ON THE BOX WHAT SIZE BIT YOU USE DEPENDING ON WHAT SIZE SCREWS YOU USE ? THX
Yes, it should tell you the size of drill bit required.
Thanks for the comment 👍
What size of pilot hole did you drill and what size of screw did you use? Does the pilot hole need to be a mm narrower for a tight fit or does it the same to be the same size?
Thanks.
I can't remember what size I drilled the holes, but the hole needs to be quite specific. It should say on the packaging, telling you which diameter drill bit to use. If the hole is too small the screw can crack the substrate and if the hole is too large the screw won't grip.
Thanks for the comment 👍
@@ultimatehandyman so a 7.5mm screw I would drill a 7mm pilot hole?
Great video, would you use masonry screws to attach a wood batten to a concrete fence post using the holes in the post? I would then hang a garden gate on the wood. Thanks
It depends what size the holes are in the post?
They are normally pretty wide and I doubt if they will be the correct diameter for the masonry screws?
not sure on the size of the holes as I've not got the fence post yet. Just planning ahead and not sure how people do it.
just drill the post with the correct size bit for the concrete screw and your done.
Thank you mate … the video I needed
Sorry another question if I use four of those screw will they hold a fan that weights 6kg .. plus the company said cos of the down pressure I should times that but 10 so the total weight when the fan is on will be 60 kg of is this correct or four of these? Will be more than enough to hold the fan up. Thanks
You are welcome
Thanks for the comment 👍
These fixings give a really strong fixing, so they should be fine 👍
@@ultimatehandyman thank you so much for the reply
Where have these been all my life, what are they like in thermalite as its a bastard to get a solid fixing in
Not sure, but for light fixings I normally just drive a wood screw directly into aerated concrete without drilling a pilot hole. For heavier things I use these- ua-cam.com/video/YwAMQcbJS0U/v-deo.html
will these be ok for wallplate to a concrete dence block thx
Yes, just make sure you drill the pilot hole to the correct diameter and ensure it is deep enough.
Thanks for the comment 👍
Very informative cheers. One question though what would I use to secure a Suspension trainer anchor to a single skin brick wall in my garage. It will need to support my weight - about 17st
thanks in advance
Resin anchors will probably be the best option- ua-cam.com/video/oUJPjJsdl0c/v-deo.html

I'm going to use these to secure hardibacker to the bathroom walls, do I need to drill a small pilot hole 1st as when I try to put these straight in like you do in the video it either hits the wall behind the board n just spins and when going through the board it's a struggle to keep it straight and ends up going in at n angle . thank you. just watched again and noticed the small pilot hole lol
The pilot hole is critical ;-)
thanks pal , had a go and out of 10 screws that went in 8 pull straight back out , the wall is breeze block so it's my own fault gonna take the boards back off and use flexible floor tile adhesive as recommended by the manufacturer. wish I'd have known this when I started but oh well lesson learnt.
Better in 2024 with the arrival of impact drivers :) Almost spun me around the drill a few times these back in the day when I was using a combi or even mains drill.
An impact driver works worse because the way the impact works and drives screws, well impacts them, it cracks up the concrete inside the hole and makes the thread weaker. Use a drill with a handle
Drywall screws wont go through sand cement to wooden joist to fix plasterboard are the masonry screws waterproof
I'm sure they are available for use externally, so they will have some kind of treatment to prevent rust.
Thanks for the comment
I am going to attach some fence posts to my garden wall (brick) I am thinking this will do the job without having to worry about wall plugs. Are they just sold as concrete/masonry screws or is there a specific name I need to ask for. many thanks for the vid ;)
Yes, they are just sold as Masonry/concrete screws although there are several trade names such as Multi-fix, Dewalt Tapper, Tapcon screws ETC.
Thanks for the comment
Somebody fitted my rainwater system downpipe using these screws straight into the (soft) brickwork. One of them has pulled out, so I need to move and refit the 2 screws holding the bracket. I have no idea who the manufacturer of the screws is. They are 95mm long (seems excessive to hold plastic, but hey). So I don't have info on the correct size pilot hole to drill. In wood I'd normally match the drill bit to the width of the shank, under the threads, leaving the screw to cut its own thread. Would you say this would work for brick? Or should I drill a slightly smaller hole to allow to compress the inside edge of the hole?
It's best to test on a scrap piece of masonry first.
I think normally you need a drill bit that is 0.5 - 1.0mm smaller diameter than the screw.
The important thing is the depth, if you don't drill the hole deep enough you can crack the masonry.
Thanks, that makes sense. I'll try on a spare brick first.
You said correct size hole, what is the correct size?
It depends on the screws. There are so many different makes and sizes, you just need to drill the correct size hole for the ones that you are using, this is normally printed on the packaging.
Thanks for the comment 👍
Hi, I do feel stupid writing these questions, however as mentioned before, I am a total newbie, and learning as I go. I have some of these types of screws, in the size of 7.5 x 60mm. What size hole would you do with your drill, to fit this size in, 7mm? which leaves .5mm of thread to cut in or would you use a different size hole?
I always drill the hole specified with the fixings as the correct sized hole is critical.
Too small and you can crack the concrete, too large and the screw will pull out easily.
Thanks for the comment
Unfortunately, these were bought off ebay, and there is no size on the box, for the hole you need to drill. Guess I will have to play around a bit with it.
I've just looked on Screwfix and the general consensus is a 6mm pilot drill. for a 7.5 diameter screw.
Screwfix support is a bit crap on this item, they are saying you don't need a pilot hole LOL

Thanks for helping. When learning about how to work, it can be a nightmare. So many things to consider, if.....if you intend doing a good job. Appreciate your help as ever.
You are welcome ;-)
Are these good for base plate on a stud wall fixing onto concrete?
It would be a pretty weak solution. What you have to consider is your exposure to the weather and earthquakes. A light wooden structure can be lifted off the round and so you'll see some pretty fat bolts holding some things down. Proper foundation 'anchor bolts' come in a few different shapes - L , J or T (upside down). So the hooks/barbs are cast in the concreting process, and so stop the bolt from being able to ripped out. Masonry screws by comparison are only held in my the thin thread they cut - to pull out a foundation anchor, you'd have to destroy or lift the foundation. (also important to secure them to more than just the top row of blocks / masonry if the foundation is on a wall - for which you could use heavy duty restraint straps or longer anchor bolts.
@Ultimate Handyman, Another great video. Just one question: Does a concrete screw provide a stronger fixing than using wall plugs? Are there any downsides to using concrete screws rather than wall plugs? Thanks
Concrete screws can be better in some circumstances, especially in solid substrates, as there is no expansion force. This means they can be used for close to the edge fixing, where plugs cannot be used or the substrate can crack. I would imagine they will give a stronger fixing, as they cut a thread into the substrate.
Ultimate Handyman Thank you for taking the time to reply.
did you use a hammer drill to make the hole in the block or can i use a regular drill as well to make the hole?
Yes, hammer action was used to drill the hole.
Great video, what is the bit holder you’ve got in the drill looks good! I tried to do this and the bit didn’t hold up in bent then cracked off any tips?
The bit holder is made by Wera. I always try to buy decent quality bit holders and bits, such as Wera or Whia etc.
Thanks for the comment 👍
@@ultimatehandyman After spending years using rubbish quality tools, Wera are like using alien technology. They are so strong. They can be ridiculously expensive but they sell sets of bits for really competitive prices.
@@nowthenad3286 Yeah, they make some superb tools ;-)
Do you have to predrill a hole first or can you screw without a hole?
+sean craig
You have to drill the correct sized hole I'm afraid!
Great tips I appreciate it 👍
No problem 👍

Couple of questions if i may,i need to lay 6 inch deep concrete base 20 feet x 12 feet,worried about frost,,can i cover with dp sheet?,also do i need to put control joint in,thank you
I've laid similar sized concrete bases without a control joint.
Frost can be a real problem, I'm not sure if covering it will help much. I have heard of people using a sheet and then adding some straw, but personally, I would only pour it when there was no frost forecast for a good few days.

Hi might sound a bit thick but my dad always did my diy and he is no longer here I'm wanting to put some shelfs in my kitchen but my walls crumble it's a old build and I can't even hammer a nail in the wall without it bending
Will these screws you are using work for my walls
No, I would only use these on solid concrete or solid bricks.
Do you know what your walls are made from?
They have plaster then seems like masonry or concrete they are very old builds x
I'd try regular wall plugs first- ua-cam.com/video/V4wVyyfbWog/v-deo.html
They should work ;-)
how well do these work on perforated redbricks?
It depends.
If you can hit the end of the brick, or where the brick is solid, they work really well. But if you hit one of the holes, they do not work as well.
I've used them with success on perforated bricks, you just have to be careful where you choose to fix.
Thanks for the comment 👍
I've got masonry screws and drilled the holes into the concrete floor but the holes are slightly too big for the screws . How do I correct this slight problem?
You'll have to get larger diameter masonry screws, or use something else, such as wall plugs and traditional screws.

my boy! keep the vids comin.

Would these work in Tarmac please ?
No, you need special fixings for tarmac, example here-

Sorry if u have already answered this but I want to use torx masonary screws to fasten studs to concrete. Do I need to just dril a 6mm deep start off whole into concrete then drill the screw in and it cuts itself a thread or do i need to drill a whole deeper than length of screw, so a 80mm screw would need a 90mm whole ?
You need to drill a hole of the exact diameter specified by the screw manufacturers.
The hole needs to be slightly deeper than the length of the screw, because if the screw hits the bottom of the hole it can crack the concrete.

I'm attaching a garden gate post Pedestal to a concrete slab. Assuming there is only loose sand/dirt/rubble under the slab, would you use concrete screws or masonry anchors with the chance the slab is a couple of inches of concrete then worm habitat beyond ?
Appreciate your vids :-)
Vincent Palmer
Thanks ;-)
I think the concrete anchors would probably be best, they will expand and should hold the pedestal once they are tightened down.
Cheers, off shopping I go. :-)
Vincent Palmer
You are welcome ;-)
don't the screws loose significant holding power when removed and reinstalled?
Eventually they could lose their grip if they kept being removed, although I have never tested out this theory.
Where's this chap from? Oldham?
Darwen, next to Bolton 👍
Would these be good for hanging joist hangers? or do i need to use expansion bolts?
Excellent videos thanks. Do you think that this would work in decent sandstone walling? To what depth? 100mm +? What about rather decomposed/damp sandstone?! (Some stones are better than others). The reason is to retain some wooden roof timber to prevent potential roof movement. Perhaps there is an alternative such as Rapier Starfix or Hammer-In? Thanks for any quick thoughts!
Thanks, these should work to be honest as long as you use long ones like you say 100mm into the sandstone.
I have used them in sandstone in my last terraced house and they worked fine.
Another option might be resin fixings? ua-cam.com/video/oUJPjJsdl0c/v-deo.html
Thank you greatly. Perhaps also, the resins will bleed deeper into the slightly decomposed sandstone and help strengthen the immediate area around the fixing screw/bolt.
You are welcome. Yes I guess the resin might do that.
Thanks for the comments
I just came to my mind "why they dont even make a screws for concrete without the need of tox or expansion bolts" but here we are, there it is courtesy of youtube 😁
I used these a few days back when fitting a kitchen, I hung all the wall cabinets, but needed a screw to go through the back of the cabinet and into a concrete block wall. These worked perfectly 👍
Hi I want to know do those screws need any wall plug before screw in
No, you just get the correct size concrete screw, then drill the exact pilot hole as recommended with the screws and screw them in.
Can these screws be used for breeze blocks ? Thanks
Yes, these will screw into breeze blocks as long as the correct diameter hole is drilled first. Obviously they will not be as strong as using them in solid concrete/blocks etc.
Thanks for the comment
Awesome
👍
would they work for a wall bracket for a tv
How about fixing with it into 9 inch hollow block???
These will work fine, but they will not be as strong if you get the hole in the hollow part of the block, as the walls of the block are not very thick.
Thanks for the comment 👍
Thanks, explained everything we need to do. 😁 😀
Glad it was helpful!
How much do they cost?
Is it predrilled?
Yes, you need to pre-drill the substrate with the correct diameter drill bit 👍
Thanks for the comment 👍
Can I use this to bolt down a steel 6'x8' metal shed on to concrete ground without an tap n set
Concrete anchors would be preferred as they grip tighter the more you try and pull them out- ua-cam.com/video/hJg0xVb3eAg/v-deo.html

Any good for breeze blocks??
It depends how much weight you want to fix to them. They are okay in some situations on breeze blocks, but they won't hold too well if they go in the hollow bit- but you could use snap toggles if you hit a hollow part-

Would you use these to attach battens & plaster board to an old wall in our cottage. Or would ordinary screws & rawl-plugs be better?
+Roger Waldram
I'd use screws and wall plugs to be honest. These fixings are no good for battens as the screw part sticks through the top of what you are fixing. You need a flush fixing for battens, so good quality countersunk screws and wall plugs will work best ;-)

Can you tell me if they would be correct for fixing moisture resistant plasterboard to a brick wall that has plaster on it?
I have put up 'hardie backer board' with adhesive but I think both it and the plasterboard would need something like this?
Are you sure that you can install hardie backer boards using adhesive?
Someone asked me about fixing aquapanel using adhesive a few years back and so I asked the manufacturers, who said that you should not use adhesive- www.ultimatehandyman.co.uk/forum1/dot-dab-aquapanel-direct-bond-aquapanel-t3056.html
It’s not that easy to drill these in like the video ! I been trying to and can’t , even after I used a drill beat. Still couldn’t get it through my pavers
Are you using a masonry drill bit and a drill with hammer action?
Hi,
Could you use these to attach a gate post to a stone wall?

A wood screw and a cement screw look exactly the same to me
Concrete screws/masonry screws have a much wider thread than a wood screw and are blunt at the end (they don't have a point like a wood screw)
