2040 extrusion T-nuts screw size
M5 · 8 to 20 mm long
Our records put 2040 extrusion T-nuts on M5 screws in lengths from 8 to 20 mm.
The record covers standard drop-in nut for the 2040 6mm slot.
This entry is marked confirmed and comes from zivon.ca.
For reference, M5 is 5 mm across the threads at 0.8 mm pitch. The imperial size people confuse it with: #10-32 (4.83 mm) — the other common rack thread; check before mixing.

How to check the screw before you buy
- Into printed plastic, the screw either self-taps or needs a heat-set insert; machine screws straight into plastic strip easily.
- Diameter: across the threads an M5 screw measures about 5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.8 mm from one thread crest to the next (12.5 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 8–20 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M5 heads take PH2 for Phillips and T25 for Torx, and a 4 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 M5 is about 4.0-6.0 N·m into metal threads and 1.5-2.5 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M5
- 2020 extrusion end-tap holes vary between 4.2mm (M5) and 5mm (M6) core depending on manufacturer — always measure before tapping.
- M5x0.8 is the de facto universal bike thread — confirm 0.8mm pitch before threading into carbon or alloy bosses.

Questions about 2040 extrusion T-nuts screws
- What size screw does 2040 extrusion T-nuts use?
- M5 × 8–20 mm for standard drop-in nut for the 2040 6mm slot.
- How long are the screws in 2040 extrusion T-nuts?
- The records range from 8 to 20 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M5 screw?
- 0.8 mm (coarse), which is the standard pitch for M5 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 4.2 mm and the normal clearance hole is 5.5 mm.
- What screwdriver do I need for 2040 extrusion T-nuts?
- The sources do not name the drive. For M5, Phillips heads normally take PH2 and Torx heads T25; socket heads take a 4 mm hex key.
- Can I use an imperial screw instead of M5?
- No. Imperial look-alike: #10-32 (4.83 mm) — the other common rack thread; check before mixing. Use a true M5 screw so it does not cross-thread or strip the hole.
