How to check the screw before you buy
- Laptop covers and brackets often mix two or three lengths of the same thread, so lay the screws out in the order they came out (a magnetic mat or a sheet of paper with the hole pattern drawn on it works).
- Diameter: across the threads an M1.4 screw measures about 1.4 mm with calipers (usually a hair under). This device also uses M1.6 / M2 / M2.5, so measure each screw rather than assuming they match.
- 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 1.2–7 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M1.4 heads take PH000 / PH00 for Phillips and T2–T3 for Torx, and a 1.3 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 M1.4 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 / M1.6 / M2 / M2.5
- Dental implant screws (M1.4/M1.6) are proprietary per system — Bredent, NeoBiotech, Nobel and Straumann are not interchangeable even at the same nominal size.
- Headphone hinge screw sizes are usually quoted from screwdriver bit size, not an actual thread spec - measure before buying.
- M.2 SSD mounting screws (M2 x 3mm) are frequently mislabeled generically as 'M.2 screws' which can be confused with the M2 metric thread designation — they do coincide numerically here but are conceptually distinct (M.2 = card format, M2 = thread size).
- Dell/HP/Lenovo manuals often list screws only by torque or head shape, so community teardowns are needed for diameter.

- How long are the screws in Dell Pro 13 Premium PA13250?
- The records range from 1.2 to 7 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 Dell Pro 13 Premium PA13250?

- 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.
