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 M6 screw measures about 6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 1 mm from one thread crest to the next (10 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: for binding head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The records span 12–20 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M6 heads take PH3 for Phillips and T30 for Torx, and a 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 M6 is about 7-10 N·m into metal threads and 2.5-4.0 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M6
- VESA display mounts are M4, M6 or M8 depending on the pattern size; measure before ordering.
- PA speaker rigging points often use M8 or M10 eyebolts even when the yoke bracket uses M5/M6 - do not assume one size per fixture.

Questions about Alpine binding heel/toe piece (heavy duty) screws
- What size screw does Alpine binding heel/toe piece (heavy duty) use?
- M6 × 12–20 mm for some binding systems use M6 at higher-load mounting points.
- How long are the screws in Alpine binding heel/toe piece (heavy duty)?
- The records range from 12 to 20 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M6 screw?
- 1 mm (coarse), which is the standard pitch for M6 machine screws; a 0.75 mm fine pitch exists but is uncommon. The tap drill is 5 mm and the normal clearance hole is 6.6 mm.
- What screwdriver do I need for Alpine binding heel/toe piece (heavy duty)?
- The sources do not name the drive. For M6, Phillips heads normally take PH3 and Torx heads T30; socket heads take a 5 mm hex key.
- Can I use an imperial screw instead of M6?
- No. Imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6. Use a true M6 screw so it does not cross-thread or strip the hole.
