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 M6 screw measures about 6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 1 mm from one thread crest to the next (10 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: for socket cap screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The records span 35–50 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Hex socket (Allen) drive. For comparison, standard M6 heads take PH3 (Phillips) or T30 (Torx), or a 5 mm hex key.
- Tightening: no device-specific torque is published in these records. The site's general figure for M6 is about 7-10 N·m into metal threads and 2.5-4.0 N·m into plastic bosses; snug it up and stop.
