SIBOOR Voron 2.4 350 / Voron 0.2 R1 kits screw size
M3 · length not stated in the sources
If you are replacing a screw on SIBOOR Voron 2.4 350 / Voron 0.2 R1 kits, the thread is M3. None of the sources we found gives an exact length, so measure the original before you order.
The record covers frame, motion and toolhead fastener set.
This entry is marked confirmed and comes from github.com Lzhikai/SIBOOR Voron BOM.md.
An M3 screw is 3 mm in diameter with a 0.5 mm pitch, tapped with a 2.5 mm drill; imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy
- Printer and CNC builds usually publish a bill of materials; when it lists a length, follow it, since extrusion T-nuts and motor faces have fixed thread depths.
- Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- 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: 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 M3 heads take PH1 for Phillips and T10 for Torx, and a 2.5 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 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
- M3 is by far the most common metric fastener across lab, metrology, and cleanroom equipment, spanning coarse-thread ISO M3x0.5 in most cases.
- The bioprinter M3 reference is a tube-connector thread spec, not a structural chassis screw; verify before assuming interchangeability with fastener screws.

Questions about SIBOOR Voron 2.4 350 / Voron 0.2 R1 kits screws
- What size screw does SIBOOR Voron 2.4 350 / Voron 0.2 R1 kits use?
- M3 for frame, motion and toolhead fastener set.
- How long are the screws in SIBOOR Voron 2.4 350 / Voron 0.2 R1 kits?
- 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 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 SIBOOR Voron 2.4 350 / Voron 0.2 R1 kits?
- The sources do not name the drive. For M3, Phillips heads normally take PH1 and Torx heads T10; socket heads take 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.
