I was curious about this thread, but it seems I was thinking on another kind of threaded inserts... I would like to know about the inserts on my Epic's body, the ones used to set the control cavity plate... I would like to find some of those (with their screws) to change the cover plate system on a couple active basses I have, definitely a much wiser option than big plastic battery holders, normal screwing on wood or anything else Ive seen around if you have to take the cover every once in a while to do a battery change...
