What size screw does Steam Deck (LCD) Type 5 fastener use?

M1.6 × 3 mm for 1.6mm diameter, 0.35mm pitch machine screw.

How long are the screws in Steam Deck (LCD) Type 5 fastener?

The record gives 3 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.

What is the thread pitch of an M1.6 screw?

0.35 mm (coarse), which is the standard pitch for M1.6 machine screws; a 0.2 mm fine pitch exists but is uncommon. The tap drill is 1.25 mm and the normal clearance hole is 1.8 mm.

What screwdriver do I need for Steam Deck (LCD) Type 5 fastener?

The sources do not name the drive. For M1.6, Phillips heads normally take PH00 and Torx heads T4–T5; socket heads take a 1.5 mm hex key.

Can I use an imperial screw instead of M1.6?

No. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent. Use a true M1.6 screw so it does not cross-thread or strip the hole.

Where can I buy replacement screws for Steam Deck (LCD) Type 5 fastener?

TechSpareWarehouse (our own store) lists M1.6 x 3mm, which matches the length in the records above.

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 M1.6 screw measures about 1.6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.35 mm from one thread crest to the next (28.57 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 record states 3 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 M1.6 heads take PH00 for Phillips and T4–T5 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 M1.6 is about 12-20 N·cm into metal threads and 6-10 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M1.6

Steam Deck (LCD) mixes M1.6 and M2 screws with near-identical heads at 3, 3.5, 4 and 4.5 mm — swapping them cross-threads the plastic. Match by the iFixit Screw ID guide.
Steam Deck backplate screws are M1.6, not M2 as commonly assumed — check the iFixit Screw ID guide before ordering.
