The classic example of this is the jackposts on HPIB
connectors. The
male end (to fit into the socket/panel) is often 6-32 UNC (expeically
in HP machines), although I have seen metric theads in, say an Epson
printer [1]. The female part, to take the screw in the cable
connectors is M3.5 (!) now, early ones were 6-32 UNC. The convention
for real HP cables/jackposts was taht nickel-plated (shiny metal)
screws/posts are UNC, black oxide ones are metric, but I've seen
plenty of shiny metric ones on other eqyipment.
I was thinking about that too. I've also got some GPIB gear that
uses the "blue ribbon" wire bail clips as well.
