How long are the screws in Voron 2.4 3D printer?

The records range from 8 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 Voron 2.4 3D printer?

The source lists a Hex socket (Allen) 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.

Where can I buy replacement screws for Voron 2.4 3D printer?

TechSpareWarehouse (our own store) lists M3 x 8mm, M3 x 10mm and M3 x 12mm, which match lengths in the records above.

Voron 2.4 3D printer screw size

M3 / M5 · 8 to 40 mm long

The screws used on Voron 2.4 3D printer are M3 and M5 in lengths from 8 to 40 mm.

There are 2 separate fitment records for it, including official manual: M3x8 SHCS hold each of the four Z-drive stepper motor mounts; M3x40 SHCS (M3) and frame feet: M5x10 BHCS with M5 hex nuts (M5).

Head and drive, as the sources state them: socket cap and button heads and Hex socket (Allen) drive.

2 of the 2 records are marked confirmed, drawn from 1 source (zh.treatstock.com).

For reference, M3 is 3 mm across the threads at 0.5 mm pitch. The imperial size people confuse it with: #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). This device also uses M5, 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: for socket cap / button head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
The records span 8–40 mm, which means different positions take different lengths — match each hole to its own screw.
Driver: the source names a Hex socket (Allen) 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 / M5

M3 is the most common FPV screw, but length must match arm and stack thickness — too long can short motor windings or crack frame plates.
Museum/AV projector mounting kits typically bundle four to six thread sizes (M3–M6) in one bag to fit varied projector OEM patterns — always match the specific length/thread pair actually used for a given projector model rather than assuming all sizes apply universally.
The 'GoPro thread' is M5-0.8, a de facto standard on third-party mounts, and is not the imperial 1/4-20 tripod thread.
M5x0.8 is the de facto universal bike thread — confirm 0.8mm pitch before threading into carbon or alloy bosses.
