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.

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). This device also uses M2.5, so measure each screw rather than assuming they match.
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: the source describes a countersunk (flat) head, and those are measured overall, from the top of the head to the tip.
The records span 2–11 mm, which means different positions take different lengths — match each hole to its own screw.
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 / M2.5

The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.
Most consumer gadget teardowns (robot vacuums, toothbrushes, e-readers, VR headsets) list only the driver bit, not the thread — measure before ordering.
Nylon-coated M2.5 screws (ThinkPad Edge) are thread-locking; plain replacements work loose over time.
Dell/HP/Lenovo manuals often list screws only by torque or head shape, so community teardowns are needed for diameter.
