How to check the screw before you buy
- Where the manufacturer publishes a torque value, use a torque driver rather than feel.
- 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: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The records span 20–35 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M6 heads take PH3 for Phillips and T30 for Torx, and a 5 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 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.
Common mix-ups with M6
- Rack hole threads vary: 10-32 and 12-24 are still common in US racks alongside M6 - check the rail before buying.
- Rack rails come in M6, M5 and imperial 10-32 — check which cage nuts your rack uses before buying a bag of screws.
