What size screw does Raspberry Pi camera module mounts use?

M2.5 × 4–8 mm for third-party camera mounts use M2.5/M2 board holes.

How long are the screws in Raspberry Pi camera module mounts?

The records range from 4 to 8 mm depending on the position, so match each screw to its own hole.

What is the thread pitch of an M2.5 screw?

0.45 mm (coarse), which is the standard pitch for M2.5 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.05 mm and the normal clearance hole is 2.9 mm.

What screwdriver do I need for Raspberry Pi camera module mounts?

The sources do not name the drive. For M2.5, Phillips heads normally take PH1 and Torx heads T8; socket heads take a 2 mm hex key.

Can I use an imperial screw instead of M2.5?

No. Imperial look-alike: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in. Use a true M2.5 screw so it does not cross-thread or strip the hole.

Where can I buy replacement screws for Raspberry Pi camera module mounts?

TechSpareWarehouse (our own store) lists M2.5 x 4mm, M2.5 x 5mm and M2.5 x 6mm, which match lengths in the records above.

M2.5 · 4 to 8 mm long

Raspberry Pi camera module mounts takes M2.5 metric screws in lengths from 4 to 8 mm.

It is listed for third-party camera mounts use M2.5/M2 board holes.

This entry is marked reported and comes from thepihut.com.

M2.5 means a 2.5 mm nominal diameter with a 0.45 mm thread pitch. Imperial look-alike: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in.

How to check the screw before you buy

Do not confuse metric mounting screws with the 1/4-20 or 3/8-16 tripod threads that cameras and clamps also carry.
Diameter: across the threads an M2.5 screw measures about 2.5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.45 mm from one thread crest to the next (22.22 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 4–8 mm, which means different positions take different lengths — match each hole to its own screw.
Driver: the source does not name the drive. Standard M2.5 heads take PH1 for Phillips and T8 for Torx, and a 2 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 M2.5 is about 45-70 N·cm into metal threads and 20-35 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M2.5

Projector optics and fan screws often step down to M2.5 while the outer covers use M3 - do not reuse cover screws inside the light engine.
M2.5 pitch is 0.45mm vs M3's 0.5mm and M2's 0.4mm — forcing the wrong one strips plastic bosses instantly.
