Fairphone 2 / 3 / 4 internal screws screw size
M1.4 · 3.8 to 5.5 mm long
Our records put Fairphone 2 / 3 / 4 internal screws on M1.4 screws in lengths from 3.8 to 5.5 mm.
The record covers community-compiled table gives 1.4mm diameter screws: FP2 5.5mm, FP3 3.8-4.1mm, FP4 4.5mm, Phillips #0/#00.
Head and drive, as the source states them: Phillips drive.
This entry is marked likely and comes from forum.fairphone.com.
For reference, M1.4 is 1.4 mm across the threads at 0.3 mm pitch. The imperial size people confuse it with: #0-80 UNF (1.52 mm) — close in diameter, different pitch, do not mix.

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 M1.4 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 3.8–5.5 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Phillips 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
- Sellers often list only thread diameter, so an M1.4x3 drone screw and an M1.4x2.3 phone screw look like the same product.
- Phone guides describe screws by Torx bit size (T3/T4/T5) rather than thread; M1.4-M1.6 is inferred from shaft diameter, not stated by the maker.

Questions about Fairphone 2 / 3 / 4 internal screws screws
- What size screw does Fairphone 2 / 3 / 4 internal screws use?
- M1.4 × 3.8–5.5 mm for community-compiled table gives 1.4mm diameter screws: FP2 5.5mm, FP3 3.8-4.1mm, FP4 4.5mm, Phillips #0/#00.
- How long are the screws in Fairphone 2 / 3 / 4 internal screws?
- The records range from 3.8 to 5.5 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 Fairphone 2 / 3 / 4 internal screws?
- The source lists a Phillips 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.
