Perfect for what I needed.

Worked great, fixed my stripped engine block on the timinh belt idler, been 12,000 miles without a issue.

Awesome kit, does it exactly what it's supposed to. I used a 1/4" wrench when tapping the hole, and I have to emphasize tapping the new hole as straight as possible. If you're crooked, the bolt will go in at a poor angle and won't seat as well. Otherwise, this whole kit for $35 is a steal based on the one size kits I've seen listed on here as well. The tools I used for the M6 repair were all sturdy, and I ran into no issues.

Works well for the small engines that I work on. Mostly on aluminum engines heads. easy to bore out the hole and insert the coil, strong as the original
