## Questions & Answers

**Q: Anyone try this kit to repair side post battery terminals?**
A: Kit worked great.  I will buy another set if I need it

**Q: What’s the installed thread length of the inserts? Specifically 5/16-18**
A: Did not measure the insert length, but most inserts are approx 1/2" long in this size range. It only has to be as long as the diameter of the boat to be full strength.  So if it is a 5/16 insert the insert needs to be at least 5/16 long. These are. But the tool is junk, I suggest buying a name brand US. Made tool.

**Q: will this work on .9 thread?**
A: This kit is for 5mm .

**Q: If the thread id of the helicoil is m8x1.25, so what is the od of that helicoil?**
A: You purchase the kit you need depending on the thread type you are attempting to repair.

### ⭐⭐⭐⭐⭐ Saves the day once again!!
*by N***R on July 10, 2025*

Why did you pick this product vs others?:Really nice repair kit!! Never had an issue with these helicoil's... Well worth the money

### ⭐⭐⭐⭐⭐ It actually works!
*by D***  on June 26, 2025*

I was very close to just buying the Helicoil kit which is like $60+ but I am very glad that I made the decision to give this kit a try.My Subaru’s high performance Brembo brake caliper mounting bolt thread had stripped out (common for STi Brembo calipers- due to the bolts being the harder metal: steel & calipers being aluminum- which is a softer metal) and this kit has given me a brand new caliper thread for bolting the caliper to the mounting bracket.10/10 would highly recommend!It comes with instructions, but watch a few installation videos so that everything is fresh in your mind.Advice I would say is take your time, work very carefully and make sure that you drill perfectly straight into the stripped thread, backing the drill out occasionally to get metal shavings out of the hole. When the time comes to use the thread-making tool, also make sure it is going in nice and straight, go slowly while creating the new thread which the coil will sit into. Then inspect the new threads, make sure they are clean- blow out any metal shavings/debris. Next, load your new threaded coil into the installation tool, by hand turn the installation tool & you’ll feel the coil catch sit into the newly made thread. Once the coil is fully seated into the hole, visually inspect it that all the threads are even and straight. Use the included breaking pin tool to break off the little coil end tang. Finally, thread the bolt intended for the previously stripped-out hole into the newly coiled, repaired threaded hole.

### ⭐⭐⭐⭐⭐ Great to have at the shop or garage.
