E3D-style hotend nozzles screw size
M6 · length not stated in the sources
If you are replacing a screw on E3D-style hotend nozzles, the thread is M6. None of the sources we found gives an exact length, so measure the original before you order.
The record covers standard M6x1 nozzle body thread used across printers.
This entry is marked confirmed and comes from printables.com.
An M6 screw is 6 mm in diameter with a 1 mm pitch, tapped with a 5 mm drill; imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6.

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 M6 screw measures about 6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 1 mm from one thread crest to the next (10 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 M6 heads take PH3 for Phillips and T30 for Torx, and a 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 M6 is about 7-10 N·m into metal threads and 2.5-4.0 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M6
- Astro dovetail hardware is inconsistent: Losmandy-brand dovetail plate screws are 1/4-20 (imperial) per Losmandy/Astro-Physics documentation, while PrimaLuceLab's PLUS-standard dovetails explicitly use M6 — don't assume metric across all 'Losmandy-style' dovetail ecosystems.
- TS-Optics Losmandy-style dovetail bars drill through-holes sized to accept either M6 metric screws or 1/4" imperial screws interchangeably in the same countersunk holes.

Questions about E3D-style hotend nozzles screws
- What size screw does E3D-style hotend nozzles use?
- M6 for standard M6x1 nozzle body thread used across printers.
- How long are the screws in E3D-style hotend nozzles?
- 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 M6 screw?
- 1 mm (coarse), which is the standard pitch for M6 machine screws; a 0.75 mm fine pitch exists but is uncommon. The tap drill is 5 mm and the normal clearance hole is 6.6 mm.
- What screwdriver do I need for E3D-style hotend nozzles?
- The sources do not name the drive. For M6, Phillips heads normally take PH3 and Torx heads T30; socket heads take a 5 mm hex key.
- Can I use an imperial screw instead of M6?
- No. Imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6. Use a true M6 screw so it does not cross-thread or strip the hole.
