How to check the screw before you buy
- Scope and accessory mounts often publish a torque value; tighten to it in a cross pattern.
- 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 record states 16 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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
- 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.
- Husqvarna alone mixes M5 (trimmer and chainsaw housings) and M6 (brushcutter/mower housings), so screws are not interchangeable across their own models.
