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 M1.2 screw measures about 1.2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.25 mm from one thread crest to the next (40 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 1.5–2.5 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M1.2 heads take PH000 / JIS 00 for Phillips and T1–T2 for Torx; 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 M1.2 is about 5-8 N·cm into metal threads and 3-5 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M1.2
- Framework lists both M1.2 x 3.0 silver and M1.6 x 3.0 black expansion-card screws; they look identical in the tray but are not interchangeable.
- M1.2 and M1.4 look identical in an eyeglass repair kit — the wrong one strips soft acetate or metal hinges.
