Generic laptop/consumer-drone/PCB assemblies (representative of tablet internal fasteners) screw size
M2 · length not stated in the sources
If you are replacing a screw on Generic laptop/consumer-drone/PCB assemblies (representative of tablet internal fasteners), the thread is M2. None of the sources we found gives an exact length, so measure the original before you order.
It is listed for PCB/chassis mounting screw, M2-0.4 coarse thread common in this device class.
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
- Laptop covers and brackets often mix two or three lengths of the same thread, so lay the screws out in the order they came out (a magnetic mat or a sheet of paper with the hole pattern drawn on it works).
- 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
- Packaging/labeling equipment manuals (e.g., cab print-and-apply applicators) mix M2 through M6 fasteners across a single machine for very different assemblies (sensors vs. frame vs. drive) — do not generalize one thread size to 'the machine' as a whole; cite the specific subassembly.
- Legacy Williams/Bally pinball fasteners are imperial (#5-40, #6-32); the M4 coil bracket is a modern Stern-era part.

Questions about Generic laptop/consumer-drone/PCB assemblies (representative of tablet internal fasteners) screws
- What size screw does Generic laptop/consumer-drone/PCB assemblies (representative of tablet internal fasteners) use?
- M2 for PCB/chassis mounting screw, M2-0.4 coarse thread common in this device class.
- How long are the screws in Generic laptop/consumer-drone/PCB assemblies (representative of tablet internal fasteners)?
- 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 Generic laptop/consumer-drone/PCB assemblies (representative of tablet internal fasteners)?
- 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.
