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 1.2–5 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Torx T5 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 / M1.6 / 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.
- M1.6 is the most common laptop-internal micro screw after M2 — Dell XPS keyboards specifically call out M1.6 x 1.5mm, and generic M2 substitutes strip the bracket.
- The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.
- Dell/HP/Lenovo manuals often list screws only by torque or head shape, so community teardowns are needed for diameter.
