I like to keep my stuff as original as possible, so proper original hardware like on firearms is essential and wouldn’t want a mismatch when tolerances and finishes are calculated.
Don't know but am I the only one (here) that before throwing out any mechanical or electronic device, strips them down for all the salvageable, easy to lose/hard to find hardware like nuts/screws/washers etc?
I have a multi-drawer parts storage bin with all sorts of accumulated odds and end…can’t say if I found use for most of it but maybe one day something in those little assorted junk drawers will save me a $2 and 45 minute trip to the hardware store.
