How to check the screw before you buy
- Over-long screws in phones are a known cause of damaged boards (Apple's 'long screw damage'), so never swap positions.
- 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 record states 17 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 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
- 'Universal' eyeglass kits mislabel diameter vs shaft: a listed 1.2 can measure 1.19-1.3mm between brands.
- M1.2 and M1.4 look identical in an eyeglass repair kit — the wrong one strips soft acetate or metal hinges.
