This entry is marked confirmed and comes from smarthomestarter.com.

How to check the screw before you buy

  1. 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.
  2. 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.
  3. 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.
  4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
  5. The records span 10–40 mm, which means different positions take different lengths — match each hole to its own screw.
  6. 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.
  7. 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 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.
  • VESA display mounts are M4, M6 or M8 depending on the pattern size; measure before ordering.

Can I use an imperial screw instead of M6?
