OK, I thought as much. I ordered a small combination set from the same ebay seller you used. I guess I will have to experiment in trying to use them in epoxy too. I have some missing inserts in a couple of my Simpson meters with Bakelite cases where the bosses have broken out. Will have to rebuild new bosses from epoxy since I don't think my plastic 'welding rods' will work.
Stan, 99% of my Heli-Coil use has been for repairs as well although I have had made a few aluminum fixtures in the past where I installed them from the get-go because the threads were going to get used quite a bit. Changing hold down clamps, repeated mounting on a tripod etc., etc. Unfortunately my riv-nut sets or welders aren't going to help much on plastics and Bakelite.
