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 M5 screw measures about 5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.8 mm from one thread crest to the next (12.5 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 20–30 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M5 heads take PH2 for Phillips and T25 for Torx, and a 4 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 M5 is about 4.0-6.0 N·m into metal threads and 1.5-2.5 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M5
- Wheelchair and mobility OEM screws specify an exact standard and strength class (ISO 7045 CL4.8, ISO 4762 CL12.9). Matching only the thread size can cause a failure under load.
- M5x0.8 is the de facto universal bike thread — confirm 0.8mm pitch before threading into carbon or alloy bosses.

- The records range from 20 to 30 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M5 screw?

- What screwdriver do I need for Bar-end plug or bar-end shifter?
- The sources do not name the drive. For M5, Phillips heads normally take PH2 and Torx heads T25; socket heads take a 4 mm hex key.
- Can I use an imperial screw instead of M5?
- No. Imperial look-alike: #10-32 (4.83 mm) — the other common rack thread; check before mixing. Use a true M5 screw so it does not cross-thread or strip the hole.
