Hi 77 year old retired engineer, part time DIY’er, they say you learn something new every day, this was my daily bit of learning. Thanks and greetings from the UK (England).
Why is it that only engineers feel compelled to tell everyone that they are an engineer? Maybe doctors too. There's probably plumbers, managers, technical writers, etc in the comments below. The only other person that mentioned his career is the cabinet maker. That info is germaine to the topic.
@@1QKGLH I'm a priest and I like this video. God Bless You, My Son. Pax Vobiscum. (I'm really nothing.) An unemployed former friend of mine became an ordained minister. Why? I'm sure I have no clue. He uses these screws all the time.
Hi, 72 year old professional woodworker here. Been using these screws for over 30 plus years. They are the best for any composition wood material like MDF or Particle Board. They were designed specifically for these materials with their large diameter bore and wide and coarse thread design. Readily available from Hafele Corporation out of Carey, NC. Hafele also provide a jig assembly for attaching to a Mikita drill ( or at least the use to) as well as a multistep drill bit for boring. The jig assemble assist in keeping your drill bit at a 90 degree angle and also sets depth of cut.
I’m a cabinet maker in Detroit. I’ve been use confirmat screws for 20 years! I use a construction/line boarding machine to line up the holes for the cabinet construction in plywood. All my cabinets are made of plywood, although I have use these in melamine boxes before. Far superior to any fastening system or dowels on the market currently I can see no limitations.
@@MadLadsAnonymous so the hand drill bit is a two part construction. I like the Amana Tool 55103. The outer bit is carbide (7mm) and then there is a bit through the center (5mm). On my construction/line boring machine I use a 7mm for the sides and the a 5mm for cross member the screw it self has nib built in so there’s no need for counter sinks.
A good way to strengthen these or any other screws into wood connection, is to use a needle injector to squirt a small amount of glue (urethane, yellow, whatever) deep into the hole before putting in the screw. Drilling as well as the act of screwing the screw into the wood, shreds, cuts, and splits the wood fibers. That small amount of adhesive, glues those fibers back together, actually making them stronger than the original wood. I first used this method while repairing old doors where the screws would no longer hold the hinges tight.
@@TodaysCraftsmen The glue idea is exactly what it needs. The key is keeping the particle board from damage inside the hole. Once it starts it will self destruct.
In every case the main failure is where the fasteners are in the edge of laminated stock. Used some free distressed IKEA style cabinets for shop bench bases. Numerous times I had to put real wood blocks in panel intersections and add screws from both sides. Sheet goods aren’t good at holding an ordinary screw in the edge. Particle board stock isn’t good at screw holding in the face either.
There is a tendency to transfer the name of the most prominent component to the entire product. Mainly for compactness: so "Melamine" in preference to "Melamine-faced Particle-board".
I never knew these strange screws had a name. I've often used them because they come with Ikea flatpack furniture, which goes together with really precise, very tight joints. The factory drills all the holes in precisely the right position, and you just put the screws they provide into the holes and tighten them up. I'm always impressed by them. I totally admit that your average finished piece of flatpack furniture (a wardrobe or the like) is very plain, not aesthetic, but if you need a wardrobe and can't afford several hundred pounds or over a thousand pounds, flatpacks do the job and are affordable. (And being flatpack, you can get them through a narrow front door, whereas a lot of pre-assembled furniture would not easily go through. But you DO need a fairly large floorspace to assemble them, because you have to assemble flat on the floor. That may mean you have to push your bed onto its side against the wall to create space on your bedroom floor.) I am amazed that the makers produce their products so accurately. It must be because they make them by the hundred thousand if not by the million, and they've got them off to a fine art in the factory. The precision of the joints is remarkable, considering they are designed to be put together by the merest amateurs at woodwork, like myself.
I agree. It’s not heirloom quality stuff but if you assemble it well it lasts a long time for the price. Even as a furniture/cabinet maker I have IKEA stuff in my house.
WHile I see a possible use for such screws, depending on the cost, I think my typical screws will be used for me. IF the confirmat screws are the same price, I could buy them. But otherwise I continue using the typical screws that have done me very well over the years... Thumbs Up either way!
YEARS AGO, When I was building furniture. before lumber prices got out of hand, I used to have 3 drills at the ready. #1 was to predrill the hole. #2 was to countersink that hole & #3 was to drive the screw home. Back in those days we did not have drill bits with countersink built onto it. This in like late last century. OH, all my drill motors were corded. !
I’m a full time cabinetmaker at a custom shop. Confirmat screws work really well in particle board and mdf. They tend to delaminate the veneer layers in cabinet grade plywood. They also telegraph. Run your hand over the surface above the confirmat screws and you’ll feel the bumps they create. Or look at the surface of the ply with raking light. I use the 5, 7, 10 mm full carbide counter sink drill bit
I’ve been saving these screws from old flat pack furniture for years, thinking they’ll come in useful at some point. Now I know how to drill the holes correctly ! Thanks.
What a great demo of how to use confirmat screws in a normal bench setup, with basic tools. I need to build a non standard size kitchen cabinet, so will defo use this method. Thanks 😊
Thanks for that explanation. I've used them in flat pack furniture but didn't know that they had a specific name. I'm fairly certain that the ones I've used have always been used with a hex drive. Cheers from England
I just started using them for any type of particle board, MDF etc.. One of the things I found was that you want to be careful when screwing them in that you don't over torque them , What I mean is that when the screw reaches the bottom of the hole you want to just tighten it by hand. Basically once these joints get a bit striped and start wiggling the are doomed. (we've all seen those Ikea chest of drawers that as soon as there is any wiggling at the joints, their days are numbered
I'd be intrigued to see how they would have held up on solid wood, given that in both tests it was the material that gave way. Even dowels and glue won't help if the material itself breaks rather than the joint. I imagine it would be rare for someone to use these screws on a solid wood project, but it would still be interesting to see how well they would do.
Thank you for this video .And your recommendation of this screws . I will be using them shortly on a project .As always very informative video .Thanks Jeff
Cool demo~! I've seen these screws for years in DIY melamine furniture. Definitely a beefy fastener, but never really thought about trying them in something other than melamine. Interesting idea...Thanks for sharing~!
Always good to learn something new. I will reference this video when using melamine next. Pretty sure I have those same Dubuque clamps as well - the best I've ever used.
Thank you for the video, I’ve got a large jar full of these screws which I took off kitchen cabinets many years ago before I discarded the carcasses. Never used them because I didn’t know what drill bits to use, now I know 👍
It's a little less accurate but you can do the same thing with multiple bits. The one shot bit and countersink is definitely the better way to go if you have to install a lot of these screws.
Clicked on this video curious as to what Confirmat screws are. Not sure if this is actually correct, but working in my uncle's shop and later assembling furniture at home I learned that these are called Euroscrews (well, that the word for ford translation anyway). Used with MDF or particle boards, but have seen them used for other materials too. And always used together with dowels, almost in a 1-to-1 relationship. If two confirmat screws are used to join two faces of a cabinet, there will be for sure a minimum of two dowels also, placed ~50mm (~2inches) next to the screws. As far as assembling furniture myself, experience showed me not to trust the clutch settings on my cordless drill, and always tighten them by hand, especially with lower quality (aka cheapest furniture pieces) particle boards. Or better said, drive them with clutch set to a lower torque than needed and then drive it flush with the surface by hand, so you can feel id the particle board you are screwing into starts to give...
They are great screws and I’ve used them in quite a few cabinets that I’ve built. I don’t have doweling machine but I think that where these would really shine. At least for me, the Domino/Biscuit, staple, screw method is just as fast. I’ve also been using Wurth Assembly screws (Assy Screws) in chip board with great results.
I think for their intended purpose they’re completely adequate. The beauty of Confirmat is that they cut their own threads and can be removed and reinstalled many times without losing strength. Thanks for watching!
Very interesting! Never heard of those screws before now & wonder what the price difference is between confirmat & regular screws are? Thanks for the demo! 👍👍
I moved to using these for woodchip board construction (particleboard) a few years ago as I figured if Ikea were using them for all thier woodchip construction, there must be a good reason - turns out I was right, they are MUCH better than normal screws in woodchip. Coarser and wider threads have much better grip than normal screws.
I've used these in plywood and chip board and they seem ok. I also tried to use them in MDF and the MDF bulged and split as I tried to drive them in so foe MDF I'd say not so good unless you want to mess around with the pilot drill size but then you'll lose the strength.
We used these screws when I was a apprentice, you basically have a 12 ga screw with a 8 ga head . Because particle board is so much like weetbix the course thread and more surface area results in more holding force . If my boss saw me screwing that close to the edge like you did I would be in trouble 😂
I wonder how well that would work in some premium Baltic birch or Medite MDF? I put together a bunch of flat pack book cases and saved all the extra Confirmats, they come in two sizes 5mm and 7mm. For a home shop, the bit is the killer, $30+. And when I demo cabinets for my friends I always keep the Confirmat screws, and other odd hardware.
@@mikeking7470 They work just fine. Again, the design of these screws is to overcome the inherent weakness in particle board as well as MDF…… but I have used them in plywood for years.
Used these in 1985 in a cabinet shop. The only difference was the screw and drill bit had a taper to it. Had to make sure the bit was lined up and in the center of the board. But they work really good.
It's not melamine, it's particle board. Or chipboard. Or Barton wood. And if you're assembling flat pack furniture or you're drilling and building it yourself, just be darn sure you don't over torque, because it's ridiculously easy to strip out the weak glued sawdust that those threads are biting into. If that happens, put glue on a matchstick or two, shove them in the hole, and refasten. Once assembled and properly reinforced with cross members or backing boards, it's pretty strong. But without cross bracing or backboard reinforcement, this stuff just folds right over if you push on it. Source: Spent time assembling samples for major box stores.
Went through many comments but didn't see this addressed. So how is the cost comparison? I can see it as a "must" on melamine, but only an option on plywood (except one guy said they telegraph)
They’re definitely more expensive. IMO there’s no benefit in using them in plywood unless you plan on disassembling and reassembling the cabinet boxes.
I'm getting ready to build some built in shelves. Making them out of 1x8 pine. Would it be good to use these in the pine instead of wood screws? I like the strength these would give.
Good video ... straightforward. You said wood screw then construction screw. Did it have angular smooth portion near top ... as does traditional wood screw. You should show it. Also, a bit more close up shot on the confirmant
Great video as usual. Can these also be used for MDF? For novice woodworker building cabinets what's the best combination of wood and fastener? I know you spoke about the different woods before but what are the best fasteners for those woods? Sorry for the long winded question....😁🤘🤘🤘
Local furniture makers would use 2 confirmats and two wooden dowels (with or without PVA). If I don't mind costs, would 4 confirmats be better or worse long term?
It's a screw for particle board or press-wood (both euphemisms for "crap"). It's not for "melamine". That stuff is a coal industry by-product used, in this case, for veneer. Particle board screw.
@@TodaysCraftsmen Well, same here. In the 90s, Melamine referred exclusively to veneer you would usually buy in 4x8 sheets. Basically for counter top. Then stuff came per-venerrd, and was called "melamine". Problem is, it was now particle board covered with a thin, chippable skin. Kind of "bait and switch" over time. My thing with screws is, they're designed for a specitic material, so I call it by that. But, I totally get you, people hear Melamine and think particle board. Peace.
I think they're better in low density fibreboard (chipboard) as they have a greater surface area, see them used in conjunction with dowels on flat pack furniture. They definitely have a place and that drill bit saves a lot of time and you know you're not going to split anything.
2:37 They look like some kind on hanger contraption for your toolbelt when you are up a ladder etc... awkward-looking things that look like they really interfere with the grip of the tool... 🤔 😎👍☘️🍻
I thought Melamine was the plastic film glued to a substrate to give a timber or clean white surface to it. The substrate is often MDF or Medium Density Fibreboard. If I went to ask my local merchant for "Melamine" he would sell me a roll of plastic. I speak fluent Ikea and have seen these screws in their flatpacks and wondered about using them for my own joinery. Apart from a terminology glitch, I enjoyed to video..
It's worth noting that the initial strength of the first joint is important for people who don't have a good workspace with clamps. When assembling an Ikea piece of furniture on the floor of their apartment, that first joint may get stressed by the novice assembler.
Have seen a lot of these in all sorts of flat-pack furniture, both melamine/laminate and solid wood. I don't think I've ever seen a pozidrive confirmat screw though - they've all been hex...
How do you like your wide belt sander? if toy had the chance to do it over again; would you buy the same one? I am in the market for one or a drum sander.
It’s great for the size and price. Given the size of our old shop we couldn’t go any bigger. It’s still a huge time saver even though I could fit something much bigger now.

Numerous times I had to put real wood blocks in panel intersections and add screws from both sides. Sheet goods aren’t good at holding an ordinary screw in the edge.

Yes but in a normal static state once installed they’re plenty strong enough.

They are very popular in Romania between finerboard/ mdf cabinet makers.

The comparison to dowels is spot on! Confirmat screws provide that extra stability we all crave when building cabinets.
They’re definitely overlooked by many.
Shank you very much for showing us.

Great comparison there, Jeff! I’ll have to give them a try.

💀💀💀
They gotta do *something* right to be valued at 21billion smackaroos. :)
Same though here. (Romania, Europe) I use these screws, here the head is allen 5, no other option, lenghts are 50 and 70mm. Only for particle board.

Nice! 🙌🏼
Someone should send these to Matthias Wandel to test in his joint testing machine.
I would be honored!
I also double as a 'joint' testing machine. According to my lady...
😂😂😂
great for any chipboard but you can use them on almost anything good strong fix, i used them on recycled plastic post to fix to tree very strong fix
Nice! I’ll have to try them elsewhere.
It's not melamine, it's particle board. Or chipboard. Or Barton wood. And if you're assembling flat pack furniture or you're drilling and building it yourself, just be darn sure you don't over torque, because it's ridiculously easy to strip out the weak glued sawdust that those threads are biting into. If that happens, put glue on a matchstick or two, shove them in the hole, and refasten.
Once assembled and properly reinforced with cross members or backing boards, it's pretty strong. But without cross bracing or backboard reinforcement, this stuff just folds right over if you push on it.
Source: Spent time assembling samples for major box stores.
In the US a particleboard core with TFL faces is colloquially known as melamine.
Thanks guys. Helpful demonstration. Definitely going to try
Whatcha got zip-tied to the drill handle?
Thanks! It’s a Spyder tool holster mount.
Went through many comments but didn't see this addressed.
So how is the cost comparison?
I can see it as a "must" on melamine, but only an option on plywood (except one guy said they telegraph)
They’re definitely more expensive. IMO there’s no benefit in using them in plywood unless you plan on disassembling and reassembling the cabinet boxes.
I always build my boxes out of plywood but I may have to give these a shot!
Worth a try! They’re a quite strong “screw”
Home Depot has never heard of them
AMZ has them
Lowes has them
!
We get ours from Hafele!
I'm getting ready to build some built in shelves. Making them out of 1x8 pine. Would it be good to use these in the pine instead of wood screws? I like the strength these would give.
Where will you be using the screws in the construction?
The confirmat screws are great if you have to break down any furniture to get into a house
100% right!
Thank you very much!
You're welcome!
Good video ... straightforward. You said wood screw then construction screw. Did it have angular smooth portion near top ... as does traditional wood screw. You should show it. Also, a bit more close up shot on the confirmant
These are type 17 cabinet construction screws from Fasco Fasteners.
Hi professional slacker here. I use deck screws because that's what I already have.
If it ain’t broke don’t fix it.
at least you own it :) lol
💯
A confirmat screw is when she agrees 😊
😂
Great video as usual. Can these also be used for MDF? For novice woodworker building cabinets what's the best combination of wood and fastener? I know you spoke about the different woods before but what are the best fasteners for those woods?
Sorry for the long winded question....😁🤘🤘🤘
Thanks! From the comments it sounds like they can be used in MDF although I haven’t myself!
Need to show a close-up of the screw. Suggest adding wood glue on the screw shank.
We glue our dowels.
Local furniture makers would use 2 confirmats and two wooden dowels (with or without PVA). If I don't mind costs, would 4 confirmats be better or worse long term?
Good question! Worth testing out.
Hi, thanks.
Thanks for watching.
Would you use a confirmat screw in a cabinet if you were already using dowels. The cabinet's exterior box will be visible on both sides.
If we had finished ends we would use dowels with pocket screws or Lamello Clamex, etc.
It's a screw for particle board or press-wood (both euphemisms for "crap"). It's not for "melamine". That stuff is a coal industry by-product used, in this case, for veneer. Particle board screw.
Did you know that people have different names for things in different places? In the US this product is almost exclusively referred to as melamine.
@@TodaysCraftsmen Well, same here. In the 90s, Melamine referred exclusively to veneer you would usually buy in 4x8 sheets. Basically for counter top. Then stuff came per-venerrd, and was called "melamine". Problem is, it was now particle board covered with a thin, chippable skin. Kind of "bait and switch" over time. My thing with screws is, they're designed for a specitic material, so I call it by that. But, I totally get you, people hear Melamine and think particle board. Peace.
👍🏼👍🏼👍🏼
It feels like they were designed for composite, or end-grain.
Make me feel more confident when building flat-pack
Def made for engineered material.
Thanks, learn something new here
Thanks for tuning in!
Nice video. Would be interesting to see what actual load would break them, rather than blows with a hammer.
Thanks! I can imagine it takes a lot
I think they're better in low density fibreboard (chipboard) as they have a greater surface area, see them used in conjunction with dowels on flat pack furniture. They definitely have a place and that drill bit saves a lot of time and you know you're not going to split anything.
For sure!
Shear resistance is the biggest issue when it comes to using screws in construction. I wonder how well Confirmat screws would do compared to nails?
Good question. The issue would be how do you get a decent size nail into plywood? Predrill and hand nail?
Thanks for sharing the video but I think it would have been a better comparison to use #10 or #12 screws instead of those puny #8s.
Yeah but no one assembles cabinets with #10 or #12
@@TodaysCraftsmen Then why do they seel M5 and M7 confirmat screws? Do you know the comparable size?
Regardless of the size of the Confirmat screws no one uses 10’s or 12’s for cabinet construction.
What do you have ziptied to your drills?
2:37 They look like some kind on hanger contraption for your toolbelt when you are up a ladder etc... awkward-looking things that look like they really interfere with the grip of the tool... 🤔
😎👍☘️🍻
It’s a Spyder tool holster mount.
Correct but I hang it from a tool cart. Hasn’t gotten in my way yet!
How do these compare to pocket hole screws fro this application?
Good question.
I use them in plywood for cabinet boxes.
Nice! Looks like I do now too!
How do they compare to Pocket hole screws though?
I’d wager they’re stronger.
Great to see an American using metric
Only when I have to 😝
The Stupid System 🤮
Which?
Melomien....... that’s the coating on the chipboard that gives it the wood effect pattern.......
Yes. In the US a particleboard core with TFL faces is colloquially known as melamine.
I thought Melamine was the plastic film glued to a substrate to give a timber or clean white surface to it. The substrate is often MDF or Medium Density Fibreboard. If I went to ask my local merchant for "Melamine" he would sell me a roll of plastic. I speak fluent Ikea and have seen these screws in their flatpacks and wondered about using them for my own joinery. Apart from a terminology glitch, I enjoyed to video..
In the USA we refer to TFL (thermally fused laminate) as melamine.
Nice video, thanks :)
Glad you liked it!
It's worth noting that the initial strength of the first joint is important for people who don't have a good workspace with clamps. When assembling an Ikea piece of furniture on the floor of their apartment, that first joint may get stressed by the novice assembler.
Thanks, sounds good advice.
Oh 100%
💯💯💯
By the way what was the price difference between the two?? It would also be a special order item around here as no one carries a line of them.
I’m not positive! We buy from Hafele.
What about working on MDF?
According to the comments it should work.
MDF is very dangerous to work with due to the deadly sawdust getting in the lungs and causing a horrible disease.
All dust is a carcinogen
Have seen a lot of these in all sorts of flat-pack furniture, both melamine/laminate and solid wood. I don't think I've ever seen a pozidrive confirmat screw though - they've all been hex...
Definitely! They come in a few different drive styles.
How do you like your wide belt sander? if toy had the chance to do it over again; would you buy the same one? I am in the market for one or a drum sander.
It’s great for the size and price. Given the size of our old shop we couldn’t go any bigger. It’s still a huge time saver even though I could fit something much bigger now.
