Xbox Series X PSU bracket screw size

M3 · 8 to 10 mm long

Our records put Xbox Series X PSU bracket on M3 screws in lengths from 8 to 10 mm.

It is listed for power supply bracket retention, Torx.

Head and drive, as the source states them: Torx T8 drive.

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

An M3 screw is 3 mm in diameter with a 0.5 mm pitch, tapped with a 2.5 mm drill; imperial look-alike: #5-40 (3.18 mm) or #4-40 — neither interchanges with M3.

How to check the screw before you buy

  1. Over-long screws in phones are a known cause of damaged boards (Apple's 'long screw damage'), so never swap positions.
  2. Diameter: across the threads an M3 screw measures about 3 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
  3. Pitch: 0.5 mm from one thread crest to the next (20 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
  4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
  5. The records span 8–10 mm, which means different positions take different lengths — match each hole to its own screw.
  6. Driver: the source names a Torx T8 drive. For comparison, standard M3 heads take PH1 (Phillips) or T10 (Torx), or a 2.5 mm hex key.
  7. Tightening: no device-specific torque is published in these records. The site's general figure for M3 is about 80-130 N·cm into metal threads and 35-60 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M3

  • Power-tool gearcase and clamshell screws are usually thread-forming (marked "ST") even when the parts list gives an M-size — a normal machine screw of the same size may not hold in the plastic boss.
  • LED strip clips strip easily — M3x12 into thin plastic should be hand-driven, never with a power driver.
