Speaker flying frame / eyebolt hardware screw size
M6 · 20 to 40 mm long
The screws used on Speaker flying frame / eyebolt hardware are M6 in lengths from 20 to 40 mm.
The record covers rigging points on smaller line array cabinets.
This entry is marked reported.
M6 means a 6 mm nominal diameter with a 1 mm thread pitch. Imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6.

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 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: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The records span 20–40 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
- 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.
- VESA displays over 50kg move up to M8 x 1.25, which is outside metric M6 hardware - don't force an M6 bolt into a heavy-panel mount.

Questions about Speaker flying frame / eyebolt hardware screws
- What size screw does Speaker flying frame / eyebolt hardware use?
- M6 × 20–40 mm for rigging points on smaller line array cabinets.
- How long are the screws in Speaker flying frame / eyebolt hardware?
- The records range from 20 to 40 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 Speaker flying frame / eyebolt hardware?
- 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.
