Printer / CNC extrusion frame bolts screw size
M5 · 8 to 25 mm long
Our records put Printer / CNC extrusion frame bolts on M5 screws in lengths from 8 to 25 mm.
The record covers joins 2020 and 3030 extrusion with roll-in T-nuts.
This entry is marked confirmed and comes from openbuilds.com.
An M5 screw is 5 mm in diameter with a 0.8 mm pitch, tapped with a 4.2 mm drill; imperial look-alike: #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 8–25 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.
- Truss and stage-light clamps use M8 or M10 bolts depending on tube diameter — larger than anything in this database, so don't substitute an M6.

Questions about Printer / CNC extrusion frame bolts screws
- What size screw does Printer / CNC extrusion frame bolts use?
- M5 × 8–25 mm for joins 2020 and 3030 extrusion with roll-in T-nuts.
- How long are the screws in Printer / CNC extrusion frame bolts?
- The records range from 8 to 25 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 Printer / CNC extrusion frame bolts?
- 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.
