Axial SCX10 III RC crawler, long links screw size
M3 · 18 mm long
If you are replacing a screw on Axial SCX10 III RC crawler, long links, the thread is M3, 18 mm long.
The record covers M3x18 socket head cap screws in the stock kit.
Head and drive, as the source states them: socket cap head.
This entry is marked confirmed and comes from applianceelectronics.co.uk.
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
- Vibration loosens small screws on drones and RC models, so builders commonly add a drop of medium (blue) threadlocker on metal-to-metal joints — never on plastic.
- 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: for socket cap screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The record states 18 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 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
- LED wall cabinets use different threads at different points - M3 on bezels, M4 on frame links and tops, M6 on frame joints. 'An M4 for the LED wall' is not enough information.
- M3 (3.0mm, 0.5mm pitch) is not #6-32 UNC (~3.5mm) — they look identical and cross-thread, the single most common PC-building mistake.

Questions about Axial SCX10 III RC crawler, long links screws
- What size screw does Axial SCX10 III RC crawler, long links use?
- M3 × 18 mm for M3x18 socket head cap screws in the stock kit.
- How long are the screws in Axial SCX10 III RC crawler, long links?
- The record gives 18 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- 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 Axial SCX10 III RC crawler, long links?
- 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.
