Camera/webcam tripod mount thread adapters screw size

M4 · length not stated in the sources

Camera/webcam tripod mount thread adapters takes M4 metric screws. None of the sources we found gives an exact length, so measure the original before you order.

Where it is used: multiple tripod-adapter product listings explicitly sell '1/4-20 female to M4 male' thread adapters, confirming M4 threads are used on some camera/webcam and mic-stand mount hardware as an alternative to 1/4-20.

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

An M4 screw is 4 mm in diameter with a 0.7 mm pitch, tapped with a 3.3 mm drill; imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

How to check the screw before you buy

  1. A screw that is even 1 mm too long in a laptop base can push into the keyboard, battery or a board trace, so match the length position by position.
  2. Diameter: across the threads an M4 screw measures about 4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
  3. Pitch: 0.7 mm from one thread crest to the next (14.29 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. Driver: the source does not name the drive. Standard M4 heads take PH2 for Phillips and T20 for Torx, and a 3 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
  6. Tightening: no device-specific torque is published in these records. The site's general figure for M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.

Common mix-ups with M4

  • Camera rig/cage accessories (SmallRig, Wooden Camera/Metabones) frequently mix M4 structural screws with 1/4-20 and 3/8-16 imperial mounting points on the same product — verify which specific fastener a manual is referencing before ordering replacements.
  • Dashcam mounts advertised as '1/4" M4 screw joint' have two different threads: the 1/4"-20 camera thread and a separate M4 grub screw for the ball joint — don't order the wrong one.

How long are the screws in Camera/webcam tripod mount thread adapters?
None of the sources states a length. Remove one screw and measure it from under the head to the tip (overall for a countersunk head).
What is the thread pitch of an M4 screw?
0.7 mm (coarse), which is the standard pitch for M4 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 3.3 mm and the normal clearance hole is 4.5 mm.
What screwdriver do I need for Camera/webcam tripod mount thread adapters?
The sources do not name the drive. For M4, Phillips heads normally take PH2 and Torx heads T20; socket heads take a 3 mm hex key.
Can I use an imperial screw instead of M4?
No. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same. Use a true M4 screw so it does not cross-thread or strip the hole.
