M2.5 · length not stated in the sources
J-GUANG 2EDGK-3.5/3.81 compact terminal block (labelled M2.6 by vendor, rejected) - NOTE: vendor uses non-standard M2.6, not counted 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 rejected per rule: source specifies M2.6 which is not an accepted standard metric size.
This entry is marked likely and comes from nbjge.com.
An M2.5 screw is 2.5 mm in diameter with a 0.45 mm pitch, tapped with a 2.05 mm drill; 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
- VESA holes are threaded inserts in the back cover; if a screw stops early, back it out rather than forcing it, because a bottomed-out screw can crack the panel housing.
- 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
- NI's other DAQ SCSI jackscrews use inch-standard 2-56 UNC threads, not metric — M2.5 applies only to the specific jacksocket kit listed.
- M2 and M2.5 are both marketed for turntable headshells; buyers must check which their specific cartridge/tonearm brand uses.

Questions about J-GUANG 2EDGK-3.5/3.81 compact terminal block (labelled M2.6 by vendor, rejected) - NOTE: vendor uses non-standard M2.6, not counted screws
- What size screw does J-GUANG 2EDGK-3.5/3.81 compact terminal block (labelled M2.6 by vendor, rejected) - NOTE: vendor uses non-standard M2.6, not counted use?
- M2.5 for rejected per rule: source specifies M2.6 which is not an accepted standard metric size.
- How long are the screws in J-GUANG 2EDGK-3.5/3.81 compact terminal block (labelled M2.6 by vendor, rejected) - NOTE: vendor uses non-standard M2.6, not counted?
- 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 J-GUANG 2EDGK-3.5/3.81 compact terminal block (labelled M2.6 by vendor, rejected) - NOTE: vendor uses non-standard M2.6, not counted?
- 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.
