SmallRig camera cages, handles, L-plates and accessories screw size
M2 · length not stated in the sources
If you are replacing a screw on SmallRig camera cages, handles, L-plates and accessories, the thread is M2. None of the sources we found gives an exact length, so measure the original before you order.
The record covers smallRig 26-piece screw set (AAK2326/MB2734) for camera accessories explicitly lists included metric sizes: M2, M2.5, M3, M4 (plus 1/4" and 3/8").
This entry is marked confirmed and comes from smallrig.com.
For reference, M2 is 2 mm across the threads at 0.4 mm pitch. The imperial size people confuse it with: #2-56 UNC (2.18 mm) is close but not interchangeable.

How to check the screw before you buy
- Camera and optics hardware often uses short screws into thin threaded plates, so check engagement before tightening fully.
- Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.4 mm from one thread crest to the next (25 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.
- Driver: the source does not name the drive. Standard M2 heads take PH0 for Phillips and T6 for Torx, and a 1.5 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 M2 is about 25-40 N·cm into metal threads and 12-20 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2
- 'M2' is sometimes used loosely by resellers to mean 'roughly 2mm' without a real ISO metric thread; only counted here when the source datasheet explicitly states 'M2' thread.
- 'M2x3 T5' is commonly conflated with the Torx bit size (T5) — the T5 refers to the drive, M2x3 is the actual metric thread and length.

Questions about SmallRig camera cages, handles, L-plates and accessories screws
- What size screw does SmallRig camera cages, handles, L-plates and accessories use?
- M2 for smallRig 26-piece screw set (AAK2326/MB2734) for camera accessories explicitly lists included metric sizes: M2, M2.5, M3, M4 (plus 1/4" and 3/8").
- How long are the screws in SmallRig camera cages, handles, L-plates and accessories?
- 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 M2 screw?
- 0.4 mm (coarse), which is the standard pitch for M2 machine screws; a 0.25 mm fine pitch exists but is uncommon. The tap drill is 1.6 mm and the normal clearance hole is 2.4 mm.
- What screwdriver do I need for SmallRig camera cages, handles, L-plates and accessories?
- The sources do not name the drive. For M2, Phillips heads normally take PH0 and Torx heads T6; socket heads take a 1.5 mm hex key.
- Can I use an imperial screw instead of M2?
- No. Imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable. Use a true M2 screw so it does not cross-thread or strip the hole.
