    The first time I ever came across Helicoil was at age 16 when the sparkplug stripped out of the head on my 50cc Yamaha FS1E. I got a kit and followed the instructions and got my little bike back on the road. My dad was impressed I had found a solution to the problem and got on a fixed it by myself.

    One thing that is cool that not a lot of people know is that you can get distorted thread heicoils to prevent fasteners from backing out. They have a thread or two that is almost square shaped, locking your screw.
    They are used frequently in parts going into space where a threadlocker won’t work due to off-gasing.
    I thought that was super cool!

    • @notsofresh8563
      @notsofresh8563 5 років тому +2

      I bet they are not cheap..
      They make exhaust manifold nuts that are the same way, single use only. Exhaust manifolds are notoriously bad for losing fasteners due to the heat destroying thread lockers and taking the temper out of spring based retention systems, as well as heat cycle dimensional changes stretching studs. These type of distorted thread nuts are one of the better ways to keep stuff in place.

    I can’t believe I’m 57 and have done a good bit of DIY repair and only now becoming aware of these little lifesavers. This could have made life so much easier many times. I have a 2006 Honda Goldwing which seems to love to strip threads on the hundreds of body connection points. The “Dodge” setup would be a life saver for the many metal screw into plastic threads. Thanks for the demo!

    Im glad that you have time to make these short informative videos now Adam.
    You will have a much bigger chance of expanding your amount of viewers. When they come over to your shop to learn how to install a heli-coil and not only learn how to but see whats going on in the background they might just check out some machining videos that they would not normally watch.
    I think it will be great for the growth of the channel.
    Well done.

    I have installed literally thousands of those things mostly 8-32 , 10-32 , qnd 4-40 sizes in the servo valve bodies we build at work. We use primarily Heli Coil brand. We installed so many we converted a broke arm tapping station to install them. The tangs are a real pain in the 4-40 inserts to get out. We use tang "poppers" air and magnetic small diameter tools to remove them.

    Years ago working on an aluminium job for a car company, they insisted all tapped holes be helicoiled. Since then I always use them for any threads in aluminium. Makes more sense than just waiting for them to strip out.

    Hi Adam,
    One thing that I picked up on with Heli-Coil kits in aluminum...For maximum longevity of the inserts, install with Loctite 262 and then grease the bolts and inside the hole with black Moly grease (to keep the Loctite from grabbing the first bolt in). It also helps to not have totally blind holes, in effect giving a 'vent' so the bolts do not generate compression of air on install, or, vacuum on removal.
    Great videos! Kudos to you for making the leap of faith! Best regards & Luck.

    awesome tutorial, I knew pretty quick you're an experienced machinist. I've never installed one of these before (was always the next guy's job) and I wanted to make sure I did it right. Repairing a 28 year old motorcycle carburetor is interesting to say the least.
    "I'll just unscrew this and check the o-rings..."
    *M4x0.7 screw snaps halfway down, nightmare begins*
    "Damn, guess I'll use a screw extractor then..."
    *screw extractor snaps because 28 year old loctite is not moving*
    "WOW, ok, how about a bigger screw extractor for the broken screw extractor?"
    *second screw extractor snaps because it was cheap*
    Lots of swearing and laughter later, I ended up drilling that whole mess out with carbide tools, one of which also snapped. LOL

    This is for those of you who have used Heli-coils and then had problems breaking off the tang once you had finished inserting the Heli -coil. Using a punch to break the tang often results in dislocating the last few turns of the Heli-coil. That makes the Heil-coil useless; leaving the tang in place results in the same problem. If the bolt bottoms out on the tang and you continue to turn it, then it pushes the last few turns of the Heli-coil out of place. For all practical purposes, this makes the Heli-coil useless. So, dealing with the tang is a must do thing and not an option.
    The OEM tang breakoff tools are a ridiculously expensive solution to the dilemma. I spent less than $2 to replace a tool that cost much more and works perfectly every time that I have used it.
    For those of us who don't have a money tree in their backyard, I have a solution. Go to Harbor Freight and buy a cheap Phillips (or flat blade) screwdriver whose shaft OD is a nice slip fit in the Heli-coil you will be using. For 5/16” Heil-coils, that’s about 1/4” diameter. Take the screwdriver and cut the screwdriver tip off of it using a cutoff grinder with a thin wheel abrasive disk. Use the same disk and center it up as best you can on the now bare screwdriver shaft. Then cut a slot in the screwdriver shaft about 5/16” to 3/8” deep.
    Now that you have your finished tool, simply stick it in the driven Heli-coil and gently turn it until it seats on the tang. Now it is muscle time: turn the homemade extraction tool counterclockwise. The tang will break off and fall to the bottom of the hole. Now the bolt will screw all the way into the Heli-coil and not bottom out in it or push the last turn or two of the Heli-coil out of place.
    If the Heli-coil was installed in an open-ended hole in some place that has moving machinery, you need to retrieve the broken tang. Since the Heli-coil is non-magnetic stainless steel, that may be problematic. Unfortunately, I don’t have an easy solution for that problem… ☹

    I much prefer the solid type of thread insert and install them with locktite. I found the Helicoils don't like taking medium to high torques.

  • @samrodian919
    @samrodian919 5 років тому +2

    Another nice, concise instruction into installing the helicoil Adam. One question though, why when installing the insert don't you use the spring centre as you did when tapping the hole? If you have still got the spring centre in the mill chuck surely it would make installing the insert easier than trying to locate it by hand as it ensures it is concentric with the hole. And it puts downward spring pressure like you did by hand. Assuming of course that you have a centr hole in the installation slug. Which could be done anyway in a minute.

    I like to 'stake' my helicoils. I install them 1/2-3/4 turn below flush and then I pop a center punch mark into the side of the hole, closing up the top thread, preventing the helicoil from backing out.

      Notso Fresh
      Helicoils are designed to not back out because they expand against the walls of the thread. I’ve never had one back out (working in aerospace) unless the constituent material fails, like a plastic

    • @notsofresh8563
      @notsofresh8563 5 років тому +6

      Belt and suspenders..
      Aerospace ≠ Farming....
      In aerospace you work cleanly to exact tolerances only use the correct tools.
      In farming you wipe it on yer pants to clean it, tolerance is "Looks like its good" and the correct tool for anything is either a hammer, a crescent wrench or fencing pliers.
      You coil a hole and spin in a dirty bolt in the field in the dark, and then when you take it back out, the grit locks the bolt to the coil and the coil comes out. A little center punch pop stops this.

    • @notsofresh8563
      @notsofresh8563 5 років тому +2

      Tyler akerfeldt: The coil is slightly too large for the hole and is a spring so when you wind it in, the spring pressure outward created friction locking it into the hole. It will stay in as long as the friction between the bolt and the coil is lower than the friction between the coil and hole.
      In most situations this is fine. However if someone in the future inserts a dirty bolt, or uses locktite on the bolt, the friction may get too high and the insert comes out instead. Technically this is mis-use but it happens all the time.

    I made that company quite a bit of dough during my years as a Harley tech. Seems like bikers are more heavy handed with their wrenches than other folks, and there is so much aluminum on the trans and motors. Even had my share of repairing Helicoils that were installed incorrectly by the owners of the bikes, other dealerships and backyard mechanics. When people first start using them they have a tendency to stretch the insert and jump threads. Correct pressure is a MUST!

  • @thrownchance
    @thrownchance 5 років тому +3

    In a normal thread, only the first couple threads carry all the load. Helicoils (or any springy thread insert) distribute the loads way better. Therefore for critical threads there are often Helicoils installed from the get go (i.e. threads for refiner plates).

    • @TheNumber1326
      @TheNumber1326 5 років тому

      In addition to that, Helicoils are used heavily in the aerospace industry because they can come with a locking feature that can hold fasteners in better against the vibration of a rocket launch and the vibration on the ISS. NASA requires that just about all fasteners have a secondary locking features in addition to being properly torqued down, which is normally done with a locking Helicoil but can also be done with approved grades of Loctite, safety wire or if non-critical Kapton taping over the fastener can be done too.

I think it was a ram x dirt compactor but Kwel stuff. Silly part I wanted to see

  • @DodgeCrazed
    @DodgeCrazed 5 років тому +1

    I was taught to use red lock tight on the helicoil to help prevent the chance of it backing out. With that said I’ve always had to use them in a more extreme duty environment than a shop tool, usually on equipment or power tools like chainsaws. Heat and vibration are great are extracting these.

    I'm just curious. What is your take on threaded inserts like time-sert for this application? I use them whenever I can, always on my machinery and whenever a customer will go for it instead of a coil.
    They have all of the for install, similar to this kit, but I think the insert is a much better item.
    Stronger insert, similar size hole and threads needed to accept the insert so it's not Taki G more material away, plus they also have big-serts for when there actually is a ton of material missing.
    Just curious about your opinion since you're way above and beyond my ameteur machining experience.
    Thanks for the great videos!

      I'm an amateur as well, but I completely agree. This is not the best place for a heli-coil, and heli-coil is not the best thing to use for this application.

      jesondag If you watched the first video, he used what he had and since this is not going to be a high torque application the coil is going to be just fine. All he is going for is to prevent galling from dissimilar metals under a heat situation. This is not a spark plug hole or pressure fitting.

    So the steel(?) coil acts as threads for bolts thus protecting the soft aluminium from wear? That's really clever.

    • @Nikko780

      Yeah, works really well for any aluminum threads that will have to be used often for service or adjustments. Not so necessary on something that only gets assembled once or twice.

  • @SkypowerwithKarl
    @SkypowerwithKarl 4 роки тому +1

    The last step shown is the most important. Failure to knock off the tang will lead to the coil being pealed out or binding from the bottom. Having the punch size closely fit the inside of the coil helps hold the last coil turn in place as the tang is knocked off.

    Well done how to. The helicoil may not be the perfect tool for every job, but they do work fine in their application.
    The biggest one I ever installed was a 50 MM in a hydraulic hammer main body bolt hole. It wasn't a repair though, it was replacing the original that came out. My guess is that less than ten percent of the time, the helicoil came out, but I was taught that an impact gun wasn't to loosen the stud, just to remove it. Loosening was done by hand or with a hydraulic wrench.
    As for strength, the highest torque on the nut I ever did was somewhere around 2500 lb-ft. and in operation, the hammer is constantly trying to break itself.
    Of course, these weren't off-the-shelf Helicoil, they were built by/for the manufacturer.

That guide compresses the spring radially to match the tapped hole in the workpiece... otherwise starting the insert into the workpiece can be difficult.

    • @kejay74
      @kejay74 5 років тому

      @Nathaniel Baier If you look closely at the Heli-Coil you will find that the last little bit into the hole (nearest the outside) is very slightly NOT fully 'coiled'. This gives it a sort of gouge-in effect when loosening the bolt out. "SOME" people may also (using a small punch) force that "tail" to embed into the parent material thereby forcing the locking effect.

    This is a contentious subject at our shop. For years they used helicoils in this type of application, i.e. a way to strengthen the joint between a steel bolt and aluminum thread as well as prevent galling. Some people are still hell bent on a helicoil being sufficient, while another set of people believe that a helicoil should only be used to repair damaged threads.
    Our current policy is to only use Keenserts and I believe they have abandoned Helicoils for applications like this.
    Not trying to take away from your video, just kind of laying our what I have seen on my end considering the application.

      These helicoils are stainless steel. The application is more for having steel threads for steel bolts, so the steel bolt doesn't damage aluminum threads.
