Geartoolkit M2 fastener reference (laptop/drone/PCB mounting) screw size
M2 · length not stated in the sources
Geartoolkit M2 fastener reference (laptop/drone/PCB mounting) takes M2 metric screws. None of the sources we found gives an exact length, so measure the original before you order.
Where it is used: M2 screw/bolt dimension guide states M2 (2.00mm major diameter, M2x0.4 coarse / M2x0.25 fine) is 'commonly used in laptop assembly, consumer drones, and PCB mounting'.
This entry is marked reported and comes from geartoolkit.com.
An M2 screw is 2 mm in diameter with a 0.4 mm pitch, tapped with a 1.6 mm drill; imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable.

How to check the screw before you buy
- A screw that is even 1 mm too long in a laptop base can push into the keyboard, battery or a board trace, so match the length position by position.
- Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.4 mm from one thread crest to the next (25 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 M2 heads take PH0 for Phillips and T6 for Torx, and a 1.5 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 M2 is about 25-40 N·cm into metal threads and 12-20 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2
- Most consumer gadget teardowns (robot vacuums, toothbrushes, e-readers, VR headsets) list only the driver bit, not the thread — measure before ordering.
- Olympus part codes like 3PUK2X8SA encode diameter x length by convention, not by an ISO stamp — verify with a thread gauge before ordering.

Questions about Geartoolkit M2 fastener reference (laptop/drone/PCB mounting) screws
- What size screw does Geartoolkit M2 fastener reference (laptop/drone/PCB mounting) use?
- M2 for M2 screw/bolt dimension guide states M2 (2.00mm major diameter, M2x0.4 coarse / M2x0.25 fine) is 'commonly used in laptop assembly, consumer drones, and PCB mounting'.
- How long are the screws in Geartoolkit M2 fastener reference (laptop/drone/PCB mounting)?
- 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 M2 screw?
- 0.4 mm (coarse), which is the standard pitch for M2 machine screws; a 0.25 mm fine pitch exists but is uncommon. The tap drill is 1.6 mm and the normal clearance hole is 2.4 mm.
- What screwdriver do I need for Geartoolkit M2 fastener reference (laptop/drone/PCB mounting)?
- The sources do not name the drive. For M2, Phillips heads normally take PH0 and Torx heads T6; socket heads take a 1.5 mm hex key.
- Can I use an imperial screw instead of M2?
- No. Imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable. Use a true M2 screw so it does not cross-thread or strip the hole.
