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 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: for shoulder screw screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The record states 40 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
- 2020 extrusion end-tap holes vary between 4.2mm (M5) and 5mm (M6) core depending on manufacturer — always measure before tapping.
- The 'GoPro thread' is M5-0.8, a de facto standard on third-party mounts, and is not the imperial 1/4-20 tripod thread.
