I do a lot of repairs on Toyota, Honda, Nissan in my spare time. M6 screws are found in these 3 manufacturers. You are bound to come across a situation where the threads are buggered up and need to be repaired. When a simple tap won't do, you can drill it out and tap, and insert the helicoil. Good as new!I already have a complete metric helicoil kit from Napa Auto, and ran out of M6 helicoils. These will provide me enough to last a few years.

Excellent product. Helicoils work perfectly and are a superior STI when they are installed correctly.

I can pair the side-by-side with another brand from across seas and there’s a noticeable difference you can literally see the different quality in size and material. This is a good brand and it will pay off in the long run.

I bought these For my car, the valve cap bolt holes were stripping out. I had enough to do all bolt holes, already had head installed, with magnets and shop vac I was able to recover nearly every metal crumb from drilling and tapping new threads. The coils were a little longer, that's good, than the ones that came with a tapping kit I had purchased. Saved me from removing head and have a machine shop do it. Pulled my butt out of the sling.I will certainly buy from again if the need arises and highly recommend to others.

Not much to review about a heli coil insert to repair stripped threads.I haven't really used the inserts yet and should not write this review at this time.On the other hand, if done with right tools, there is little that can go wrong.
