How long are the screws in Mechanical keyboard tray-mount cases/plates/stabilizers?

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 Mechanical keyboard tray-mount cases/plates/stabilizers?

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.

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: for low-profile head screws, measure from under the head to the tip (countersunk heads are the exception: they 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

ASUS ROG Ally screw sizes circulating online (M2x16, M2x10) come from a community Q&A, not an ASUS manual — measure before ordering.
The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.
