M2 × 4–6 mm for battery cover and internal chassis screws, small Torx.

How long are the screws in Meta Quest 2 controller?

The records range from 4 to 6 mm depending on the position, so match each screw to its own hole.

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 Meta Quest 2 controller?

The source lists a Torx T4 drive. Standard M2 heads otherwise take PH0 (Phillips) or T6 (Torx), or 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.

TechSpareWarehouse (our own store) lists M2 x 4mm, M2 x 5mm and M2 x 6mm, which match lengths in the records above.

How to check the screw before you buy

Keep long and short screws apart when opening a console; the shell positions differ.
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.
The records span 4–6 mm, which means different positions take different lengths — match each hole to its own screw.
Driver: the source names a Torx T4 drive. For comparison, standard M2 heads take PH0 (Phillips) or T6 (Torx), or a 1.5 mm hex key.
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

Xbox Series X internal chassis screws are M3, not M2 (confirmed on iFixit) — a widespread misconception.
Most 'M2' screws in Quest and Xbox controllers use Torx or security Torx heads, not Phillips — check the drive before ordering.
