How long are the screws in Samsung Galaxy S23 board screws?

The records range from 2 to 3 mm depending on the position, so match each screw to its own hole.

What is the thread pitch of an M1.4 screw?

0.3 mm (coarse), which is the standard pitch for M1.4 machine screws. The tap drill is 1.1 mm and the normal clearance hole is 1.6 mm.

What screwdriver do I need for Samsung Galaxy S23 board screws?

The source lists a Torx drive. Standard M1.4 heads otherwise take PH000 / PH00 (Phillips) or T2–T3 (Torx), or a 1.3 mm hex key.

Can I use an imperial screw instead of M1.4?

No. Imperial look-alike: #0-80 UNF (1.52 mm) — close in diameter, different pitch, do not mix. Use a true M1.4 screw so it does not cross-thread or strip the hole.

How to check the screw before you buy

Phone and wearable screws are tiny and often differ by fractions of a millimetre between positions; keep each one next to the hole it came from.
Diameter: across the threads an M1.4 screw measures about 1.4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.3 mm from one thread crest to the next (33.33 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 2–3 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 M1.4 heads take PH000 / PH00 (Phillips) or T2–T3 (Torx), or a 1.3 mm hex key.
Tightening: no device-specific torque is published in these records. The site's general figure for M1.4 is about 8-12 N·cm into metal threads and 4-7 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M1.4

M1.4 is THE Samsung Galaxy internal screw across S, A, M and Note lines — but lengths run 2.3mm to 4mm+ and are not interchangeable between models.
