How to check the screw before you buy
- Board standoffs and enclosure bosses set the usable length: the screw should clamp the board without bottoming in the standoff.
- 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 12–16 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
- Concept2 rowers/ergs look metric-friendly but use imperial 1/4-20 hardware throughout — M6 will NOT thread in; do not force it.
- Espresso/coffee-equipment M5 and M6 socket-head screws (DIN 7984/UNI 9327) are cross-brand standard fasteners shared across CMA, Astoria, and La Cimbali brewing-group hardware, so a single screw often services multiple manufacturers' machines.
