How to check the screw before you buy
- For a wall or arm mount, the screw has to engage the threaded insert by several turns but must not bottom out, so measure the insert depth and add the thickness of the bracket and any spacers.
- Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.4 mm from one thread crest to the next (25 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 4–8 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M2 heads take PH0 for Phillips and T6 for Torx, and a 1.5 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 M2 is about 25-40 N·cm into metal threads and 12-20 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2
- Packaging/labeling equipment manuals (e.g., cab print-and-apply applicators) mix M2 through M6 fasteners across a single machine for very different assemblies (sensors vs. frame vs. drive) — do not generalize one thread size to 'the machine' as a whole; cite the specific subassembly.
- Slot car brands also use M2.2 and M2.6 threads that look like M2 but will not interchange - Slot.it M2.2x4.5 motor mount and SCC M2.6x8 body screws are separate sizes.
