50pcs Thread Repair Installation Kit Stainless Steel Helicoil Type Set (M5 x 2D)

I stripped some threads holding a skid plate on my xmaxx. Traxxas doesn't leave much thread material on some of their vehicles for skid plates, so they tend to strip out really easy. I used these on the two front screws for my xmaxx skid plate/bulkhead. Figured it was worth a try. I had bought some of these for m3 use, but never got around to using them. So far, the M4 version is working well for me.

For an inexpensive option this thread kit was great. It worked well and as long as you have an idea of how to use it you should be happy with it. It doesn't come with instructions, but if you are buying a thread repair kit you should have at least some knowledge of how these work. Quality seems good. Worked perfectly for my needs (re-threading bridge plate on a guitar).

No instructions supplied. The good news first- I successfully repaired 4 threads in an aluminum block. The problem was the tool that was supplied to insert the coils. It is a 2 piece design with a machined shaft inserted into the handle. The glue joint between the 2 pieces failed with very minimal torque. I had to super glue it to get it to work. The inserts themselves seemed ok but when you remove the drive segment hit the tool firmly. I tried hitting it gently and the insert uncoiled.

I bought this to repair threads in an aluminum Pitts Style Muffler for my R/C airplane. I used the included drill and tap. The included instructions were not detailed enough, so I went to YouTube and found a video of somebody using this exact product. I broke the first two Heli-coils because I pushed too hard when threading the coil into the tapped out hole. The tangs are supposed to break off, but not until you have the coil sufficiently threaded. Third time was a charm. This saved me from having to buy a new Pitts Style Muffler to the tune of $50. The price of this tool is very reasonable. I like the fact that there are 50 coils included. I'm really amazed that they make Helicoils this small.

This product (Stainless Steel Helicoil Type Set (M3 x 2D)) worked great for repairing the messed up thread on traxxas 2.5 TRX engine, where the starter backplate mates to the rear of the engine.Process was simple: drill out the old hole with the supplied drill bit (go slow). Make sure to cover any exposed areas of the engine, that the metal scraps could get into. Use some compressed air to clean off the engine. Tap the new hole (spray some WD-40 in the hole prior to tapping). Next screw in the heli-coil. The entire process took about 10-15 minutes.

Very easy to use. It seemed overwhelming but it very easy. You just need a drill. I used this M3 helicoil kit on some aluminum parts for my Rc trucks where the hole was over drilled for the M3 threads originally.

The bit intended to create the threads internally actually broke and snapped off immediately after starting to use it with the drill. The bit is cheap. The internal threads are cheap, and overall the kit is not good. Had I not used so many of the threads trying to work, even after the bit broke, I would have tried to return this.Look elsewhere.

Way better then I was expecting for that price. Work just as nice as tools that cost 4x as much

Had 3 threaded holes in aluminum which were all stripped out. The holes were a 5/32, and I could not find helicoils for that size. Luckily M4 was just a tab bigger, and this kit did not disappoint. Easy to use. Now I have metal threads in a aluminum body. Saved a part that I thought I would have to throw out.

Did the work at a reasonable price

Worked perfectly! I was a bit skeptical of trying to fix such a tiny screw hole. I think it is now stronger than the original.Working with such tiny fasteners is tricky. Although I put the drill bit in the chuck of my Dremel tool, I turned it manually so as to not go too far. In this way you can feel exactly what you are doing. I also used only the inner part of the insertion tool because it better let me see how far the coil was inserting.

Worked extremely well with outstanding results in saving a thread
