Helicoil kit

Seems expensive until you use it. Carefully follow the instructions, and when you're done, you'll realize what a bargain it is; especially considering your options when faced with a stripped bolt hole.Read full review...

the original

I could not find Helicoil , so I used this product call permacoil. Well that turned out to be a waste of money and time. Helical worked great and the first time.

Almost half the price vs in store

m10x1.25 x 15 fixes a japanese 14mm bolt. I used this on my 1995 honda civic d16y7 timing tensioner bolt. It worked perfectly and I was able to reuse the 14mm bolt. I loctite the helicoil spring inside and wait 24hrs for it to dry before installing the 14mm bolt. I did not and will not use loctite on the 14mm bolt. I've since gone back and removed the bolt to do some work and it came off with no problems. The helicoil works as if I never installed it. I used a 13/32 drill bit to drill out the hole before using this kit to tap and install the helicoil.Read full review...

Works great but remember to order the drill too!

Excellent quality, expected nothing less as it's a HeilCoil product. These kits don't include the necessary drill, so if you don't have the right size in your tool chest make sure you order it.

Used by NASA and others for a reason

I needed these to repair stripped threads in an aluminum engine block. The connection is now stronger than when it left the factory.
