How to check the screw before you buy
- Phone and wearable screws are tiny and often differ by fractions of a millimetre between positions; keep each one next to the hole it came from.
- 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: for pan head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The record states 6 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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.
- Commonly confused with imperial 4-40 screws in older medical equipment, but modern GE/Mindray devices explicitly list M2.5 metric threads.
