Makeblock cap screw round head hex M4 (catalog part) screw size
M4 · 22 to 30 mm long
The screws used on Makeblock cap screw round head hex M4 (catalog part) are M4 in lengths from 22 to 30 mm.
The record covers manufacturer catalog entry explicitly lists 'CAP SCREW ROUND HEAD HEX M4' as a Makeblock platform component.
Head and drive, as the source states them: socket cap head.
This entry is marked confirmed and comes from viridisflame.com.
An M4 screw is 4 mm in diameter with a 0.7 mm pitch, tapped with a 3.3 mm drill; imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

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 M4 screw measures about 4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.7 mm from one thread crest to the next (14.29 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 records span 22–30 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M4 heads take PH2 for Phillips and T20 for Torx, and a 3 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 M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M4
- M4 and 6-32 UNC share a nominal diameter with different pitch — a classic cross-thread in US-market kits.

Questions about Makeblock cap screw round head hex M4 (catalog part) screws
- What size screw does Makeblock cap screw round head hex M4 (catalog part) use?
- M4 × 22–30 mm for manufacturer catalog entry explicitly lists 'CAP SCREW ROUND HEAD HEX M4' as a Makeblock platform component.
- How long are the screws in Makeblock cap screw round head hex M4 (catalog part)?
- The records range from 22 to 30 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M4 screw?
- 0.7 mm (coarse), which is the standard pitch for M4 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 3.3 mm and the normal clearance hole is 4.5 mm.
- What screwdriver do I need for Makeblock cap screw round head hex M4 (catalog part)?
- The sources do not name the drive. For M4, Phillips heads normally take PH2 and Torx heads T20; socket heads take a 3 mm hex key.
- Can I use an imperial screw instead of M4?
- No. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same. Use a true M4 screw so it does not cross-thread or strip the hole.
