Weight machine adjustment brackets screw size

M6 · 15 to 30 mm long

Our records put Weight machine adjustment brackets on M6 screws in lengths from 15 to 30 mm.

The record covers adjustable weight stack bracket bolts.

This entry is marked reported.

An M6 screw is 6 mm in diameter with a 1 mm pitch, tapped with a 5 mm drill; 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

  1. Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
  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 15–30 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

  • UR cobot flange bolts are commonly sold/quoted as 'M6 bolts' but the required length depends on the tool thickness; UR's own guidance is bolt class M6-8.8 to ISO4762 without a fixed length, so length must be selected per adapter/tool stack-up, not assumed as a fixed mm value.
  • Rack hole threads vary: 10-32 and 12-24 are still common in US racks alongside M6 - check the rail before buying.

Questions about Weight machine adjustment brackets screws

What size screw does Weight machine adjustment brackets use?
M6 × 15–30 mm for adjustable weight stack bracket bolts.
How long are the screws in Weight machine adjustment brackets?
The records range from 15 to 30 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 Weight machine adjustment brackets?
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.
