D-sub screw/nut specs

Apogee used metric nuts and screws for all our products until the Symphony I/O which uses Imperial. 

For example, back of Rosetta-800 dsub nut accepts 2.6mm thread from a breakout cable. The imperial size that’s close to this is 440 SAE and that is used on Symphony I/O and later.
