Some months back ISTR a member had a problem with a stripped M6 female thread on Cam Position Sensor fitting. This isn't a CPS but repair an M6 thread on an engine cover fitting using a low cost kit. A thread repaired in this way is as strong if not stronger than the original.
The prodcedure is:
Drill hole out to custom size using the drill in the kit.
Clear out as much metal swarf as possible
Tap thread in hole using special tap provided in the kit.
Clear out as much metal swarf as possible
Screw in spiral "Helicoil" thread insert untill it is flush with the top of the hole.
Break tang on insert using tool provided in kit.
Test thread with bolt then reassemble

Over the years I've collected quite few of those. Because you hardly ever need more than one and they come in a set of three or four. Kind of a waste since these days I prefer to use "Time-Serts" a LOT more. They are easier to use and result in a better and more permanent repair, especially on spark plug holes. But if you need a HeliCoil you can usually pick one up at your local parts store. TimeSerts have to be ordered unless you have an industrial fastener supply store near you that carries them.
"Swarf". Sounding like machinist-professional and all.
