Valve Steam Deck (LCD) internal self-tapping screws screw size
M2 · 2.5 mm long
Our records put Valve Steam Deck (LCD) internal self-tapping screws on M2 screws, 2.5 mm long.
It is listed for M2 x 0.4 wafer head screws, 2.5mm long, 4.5mm head diameter.
Head and drive, as the source states them: wafer (thin) head.
This entry is marked likely and comes from ttrpg.network.
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
- Over-long screws in phones are a known cause of damaged boards (Apple's 'long screw damage'), so never swap positions.
- 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 wafer (thin) head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The record states 2.5 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- 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' is used loosely by modders for anything in the 1.6-2.5mm range. Measure with calipers before buying.
- Olympus part codes like 3PUK2X8SA encode diameter x length by convention, not by an ISO stamp — verify with a thread gauge before ordering.
