MH Connectors MHT-JS-M2.5 D-Sub jackscrew screw size
M2.5 · length not stated in the sources
MH Connectors MHT-JS-M2.5 D-Sub jackscrew takes M2.5 metric screws. None of the sources we found gives an exact length, so measure the original before you order.
The record covers part explicitly sized M2.5 for D-sub connector retention.
This entry is marked reported and comes from micro-processor.it.
M2.5 means a 2.5 mm nominal diameter with a 0.45 mm thread pitch. Imperial look-alike: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in.

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 M2.5 screw measures about 2.5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.45 mm from one thread crest to the next (22.22 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 does not name the drive. Standard M2.5 heads take PH1 for Phillips and T8 for Torx, and a 2 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
- Tightening: no device-specific torque is published in these records. The site's general figure for M2.5 is about 45-70 N·cm into metal threads and 20-35 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2.5
- Commonly confused with imperial 4-40 screws in older medical equipment, but modern GE/Mindray devices explicitly list M2.5 metric threads.
- M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.

Questions about MH Connectors MHT-JS-M2.5 D-Sub jackscrew screws
- What size screw does MH Connectors MHT-JS-M2.5 D-Sub jackscrew use?
- M2.5 for part explicitly sized M2.5 for D-sub connector retention.
- How long are the screws in MH Connectors MHT-JS-M2.5 D-Sub jackscrew?
- 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 M2.5 screw?
- 0.45 mm (coarse), which is the standard pitch for M2.5 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.05 mm and the normal clearance hole is 2.9 mm.
- What screwdriver do I need for MH Connectors MHT-JS-M2.5 D-Sub jackscrew?
- The sources do not name the drive. For M2.5, Phillips heads normally take PH1 and Torx heads T8; socket heads take a 2 mm hex key.
- Can I use an imperial screw instead of M2.5?
- No. Imperial look-alike: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in. Use a true M2.5 screw so it does not cross-thread or strip the hole.
