Rexel S16 paper shredder screw size
M3 / M4 / M5 / M6 · 10 to 40 mm long
Rexel S16 paper shredder takes M3, M4, M5 and M6 metric screws in lengths from 10 to 40 mm.
There are 8 separate fitment records for it, including M3 x 16 and M3 x 20 pozi pan screws in illustrated parts list (M3), M3 x 20 Pozi pan (x2) and M3 x 16 Pozi pan (x4) screws (M3) and M4 x 12 countersunk and M4 x 30 pozi pan screws (M4), plus 5 more in the table below.
Head and drive, as the sources state them: pan, flat / countersunk, set screw (headless) and socket cap heads and Pozidriv drive.
8 of the 8 records are marked confirmed, drawn from 2 sources (shreddingmachines.co.uk and qimingmachinery.com).
M3 means a 3 mm nominal diameter with a 0.5 mm thread pitch. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- Check whether the mount uses a VESA pattern or a vendor bracket before buying screws.
- Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). This device also uses M4 / M5 / M6, so measure each screw rather than assuming they match.
- Pitch: 0.5 mm from one thread crest to the next (20 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: the source describes a countersunk (flat) head, and those are measured overall, from the top of the head to the tip.
- The records span 10–40 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Pozidriv drive. For comparison, standard M3 heads take PH1 (Phillips) or T10 (Torx), or a 2.5 mm hex key.
- Tightening: no device-specific torque is published in these records. The site's general figure for M3 is about 80-130 N·cm into metal threads and 35-60 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M3 / M4 / M5 / M6
- Blender, toothbrush and shaver teardowns list Torx/Phillips bit sizes only; a T8 bit tells you nothing about the thread.
- Not all telescope/finder hardware is metric — Celestron Edge/NexStar SE finder-shoe and dovetail screws are reported as 8/32 (imperial UNC), so metric M4/M5 fitments cannot be assumed across all Celestron products; must check per accessory/vintage.
- GoPro also uses M5 for its classic two-prong mount thumbscrew and buckle system, while smaller GoPro chassis screws are commonly Torx-driven without a confirmed metric thread in available sources — don't conflate the mount thumbscrew size with internal chassis screws.
- Astro dovetail hardware is inconsistent: Losmandy-brand dovetail plate screws are 1/4-20 (imperial) per Losmandy/Astro-Physics documentation, while PrimaLuceLab's PLUS-standard dovetails explicitly use M6 — don't assume metric across all 'Losmandy-style' dovetail ecosystems.

Questions about Rexel S16 paper shredder screws
- What size screw does Rexel S16 paper shredder use?
- M3 × 16–20 mm for M3 x 16 and M3 x 20 pozi pan screws in illustrated parts list; M3 × 16–20 mm for M3 x 20 Pozi pan (x2) and M3 x 16 Pozi pan (x4) screws; M4 × 12–30 mm for M4 x 12 countersunk and M4 x 30 pozi pan screws; M4 × 30 mm for M4 x 30 Pozi pan screws (x2); M5 × 10–12 mm for M5 x 12 pozi head screw and M5 x 10 socket set screw; M5 × 10–20 mm for M5 x 12 Pozi head (x4), M5 x 20 socket cap (x2) and M5 x 10 socket set screw; M6 × 12–40 mm for M6 hex head screws from 12 to 40mm across chassis and cutter assembly; M6 × 12–40 mm for M6 x 12 (x11), M6 x 16 (x2), M6 x 20, M6 x 30 (x4) and M6 x 40 (x4) hex head screws.
- How long are the screws in Rexel S16 paper shredder?
- The records range from 10 to 40 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M3 screw?
- 0.5 mm (coarse), which is the standard pitch for M3 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.5 mm and the normal clearance hole is 3.4 mm.
- What screwdriver do I need for Rexel S16 paper shredder?
- The source lists a Pozidriv drive. Standard M3 heads otherwise take PH1 (Phillips) or T10 (Torx), or a 2.5 mm hex key.
- Can I use an imperial screw instead of M3?
- No. Imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3. Use a true M3 screw so it does not cross-thread or strip the hole.
