Voron 2.4 350 (LDO kit) gantry and frame screw size
M5 · 40 mm long
Voron 2.4 350 (LDO kit) gantry and frame takes M5 metric screws, 40 mm long.
It is listed for LDO Voron 2.4 BOM lists M5x40 socket-head cap screws for frame/gantry assembly.
Head and drive, as the source states them: socket cap head.
This entry is marked reported and comes from 3dprintingspace.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: for socket cap screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The record states 40 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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
- M5x0.8 is the de facto universal bike thread — confirm 0.8mm pitch before threading into carbon or alloy bosses.

Questions about Voron 2.4 350 (LDO kit) gantry and frame screws
- What size screw does Voron 2.4 350 (LDO kit) gantry and frame use?
- M5 × 40 mm for LDO Voron 2.4 BOM lists M5x40 socket-head cap screws for frame/gantry assembly.
- How long are the screws in Voron 2.4 350 (LDO kit) gantry and frame?
- The record gives 40 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- 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 Voron 2.4 350 (LDO kit) gantry and frame?
- 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.
