How long are the screws in 3M D-Sub/SDR connector jackscrew socket?

None of the sources states a length. Remove one screw and measure it from under the head to the tip (overall for a countersunk head).

What is the thread pitch of an M2 screw?

0.4 mm (coarse), which is the standard pitch for M2 machine screws; a 0.25 mm fine pitch exists but is uncommon. The tap drill is 1.6 mm and the normal clearance hole is 2.4 mm.

What screwdriver do I need for 3M D-Sub/SDR connector jackscrew socket?

The source lists a Slotted drive. Standard M2 heads otherwise take PH0 (Phillips) or T6 (Torx), or a 1.5 mm hex key.

Can I use an imperial screw instead of M2?

No. Imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable. Use a true M2 screw so it does not cross-thread or strip the hole.

M2 · length not stated in the sources

Our records put 3M D-Sub/SDR connector jackscrew socket on M2 screws. None of the sources we found gives an exact length, so measure the original before you order.

The record covers distributor listing: '3M 12600-S-08 is a jackscrew socket, slotted, with M2 threads... designed for panel mounting with D-Sub and SDR connectors'.

Head and drive, as the source states them: Slotted drive.

This entry is marked confirmed and comes from distyparts.com.

For reference, M2 is 2 mm across the threads at 0.4 mm pitch. The imperial size people confuse it with: #2-56 UNC (2.18 mm) is close but not interchangeable.

How to check the screw before you buy

Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.4 mm from one thread crest to the next (25 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
Driver: the source names a Slotted drive. For comparison, standard M2 heads take PH0 (Phillips) or T6 (Torx), or a 1.5 mm hex key.
Tightening: no device-specific torque is published in these records. The site's general figure for M2 is about 25-40 N·cm into metal threads and 12-20 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M2

M2 CMM stylus threads are a de facto industry standard (Renishaw-originated) rather than a formal ISO CMM spec; do not confuse with M2 electronics screws which have different head/length conventions.
M2 (2.00mm, 0.4mm pitch) is NOT the same as #2-56 UNC (2.18mm) — close enough to cross-thread and strip if forced.
