How to check the screw before you buy
- Eyeglass hinge screws are tiny; a jeweller's screwdriver and a bit of thread-locker or a self-locking screw keep them from backing out.
- Diameter: across the threads an M1.4 screw measures about 1.4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.3 mm from one thread crest to the next (33.33 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.
- The records span 2.6–5 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M1.4 heads take PH000 / PH00 for Phillips and T2–T3 for Torx, and a 1.3 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 M1.4 is about 8-12 N·cm into metal threads and 4-7 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M1.4
- Eyewear screws are named thread x shaft x length, a different convention from ISO metric naming — easy to order wrong.
- M1.4 is THE Samsung Galaxy internal screw across S, A, M and Note lines — but lengths run 2.3mm to 4mm+ and are not interchangeable between models.
