My local has everything hardware store has something called Perma-Coil, which I hadn't heard of. Anyone have experience with that kit vs Helicoil or Timeserts? It's cheap enough, $25 for a tap, insertion tool, and maybe 12 stainless inserts. What concerns me a little, is the insert is 1.5 times it's width, so a M6 would be 9mm I guess. Not super long. I know with Time-Serts at least, you can get some really long inserts. Since this is a low load application ( 8ft-lbs), maybe it doesn't matter much. Just wondering. I think I remember Helicoil kits and Time-Serts being in the $50-$80 range.
