How to check the screw before you buy
- On vehicles and bikes, use the original strength class and finish; outdoor hardware is usually stainless or coated to resist corrosion.
- 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 6–7 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
- Sensor barrel sizes like M8, M12, M18 and M30 name the sensor body or connector diameter, not a mounting screw — check whether the M number is a body thread before buying screws.
- 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.
