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 M4 screw measures about 4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.7 mm from one thread crest to the next (14.29 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 8–12 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M4 heads take PH2 for Phillips and T20 for Torx, and a 3 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 M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M4
- Grounding/earth-stud screws on hazardous-area (ATEX/IECEx) gas detectors are commonly M4 even though the enclosure body uses larger threaded glands — don't extrapolate the earth screw size to the whole unit.
- There is no single standard Picatinny/rail screw size; makers use metric M3/M4 and imperial 6-48 or 8-40 interchangeably. Always measure the existing screw.
