How long are the screws in Xbox wireless controllers?

The records range from 6 to 8 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 Xbox wireless controllers?

The source lists a Torx 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.

Where can I buy replacement screws for Xbox wireless controllers?

TechSpareWarehouse (our own store) lists M2 x 6mm and M2 x 8mm, which match lengths in the records above.

Xbox wireless controllers screw size

M2 · 6 to 8 mm long

Our records put Xbox wireless controllers on M2 screws in lengths from 6 to 8 mm.

The record covers shell screws are Torx Security TR8, M2-ish gauge but proprietary drive.

Head and drive, as the source states them: Torx drive.

This entry is marked reported and comes from ifixit.com.

For reference, M2 is 2 mm across the threads at 0.4 mm pitch. The imperial size people confuse it with: #2-56 UNC (2.18 mm) is close but not interchangeable.

How to check the screw before you buy

If several screws hold the same part, check that they are all the same length before assuming they are.
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 6–8 mm, which means different positions take different lengths — match each hole to its own screw.
Driver: the source names a Torx 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

Most 'M2' screws in Quest and Xbox controllers use Torx or security Torx heads, not Phillips — check the drive before ordering.
Apple Watch band lugs use a proprietary spring-bar/pin interface, not a metric screw - do not shop for an M-size there.
