One of the things that's always been drilled into me is "loose wires cause fires," and that's something I always remain conscious of when changing out devices. But is there such a thing as "too tight" when it comes to tightening the screws on standard 15/20A receptacles and the like? What problems can it cause if one tightens things a little too far?
(There have been a handful of times in the past where I cammed out the screw head, stripped the threads, or bent some part of the structure by going a little too far. In all those cases, I discarded the device and tried again with a fresh one. But is there a torque danger zone before any of these things happen?)
