I still don't know if its safe to go out and get a pack of 6-32
and 4-40 UNC machine screws for American equipment, where someone has been
there before and not replaced all.


That's what sheet metal screws are for. Substitute 'em for anything!
Anyway, you can't just get one pack. You've got to have pan head, flat
head, oval head, button head, and socket head, at least -- not counting
different lengths.

Seriously though, Americans don't make consumer electronics anymore.
It's all made in China. Metric for sure.
