Typical great quality Helicoil product. Stainless steel threads will add considerable strength to my project that requires bolts threading into 6061 T6 aluminium.

I would buy the EZ helio coils going ahead because they are wound tighter and easier to insert

Stripped my primary drain plug on my Harley Davidson, and this kit restored my threads to better than normal. Very easy to use.
