[Boatanchors] How to repair stripped panel threads

[David]

I'm sure this subject has come up before, but couldn't find any hits via 
google groups.
Wondering what folks on this list have used to repair stripped threads? 
I've experienced way too many over tightened fasteners which attach BA 
panels to their chassis.  Currently I have a bunch of panel screws on a 
Navigator- some are too loose due to over tightning.    One gent suggested 
dipping and curing toothpicks in Devcon epoxy and then placing them into the 
hole before screw insertion.  Short of welding (JB?) a nut on the back end 
of the threads, looking for other ideas out there.
