Dell XPS 13 7390 screw specifications

One row per fitment record. Head, drive are shown only where the source states them; pitch is the ISO coarse pitch for the thread.

How to check the screw before you buy

1. A screw that is even 1 mm too long in a laptop base can push into the keyboard, battery or a board trace, so match the length position by position.
2. Diameter: across the threads an M1.2 screw measures about 1.2 mm with calipers (usually a hair under). This device also uses M1.4 / M1.6 / M2 / M2.5, so measure each screw rather than assuming they match.
3. Pitch: 0.25 mm from one thread crest to the next (40 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
5. The records span 1.4–4.5 mm, which means different positions take different lengths — match each hole to its own screw.
6. Driver: the source names a Torx T5 drive. For comparison, standard M1.2 heads take PH000 / JIS 00 (Phillips) or T1–T2 (Torx).
7. Tightening: no device-specific torque is published in these records. The site's general figure for M1.2 is about 5-8 N·cm into metal threads and 3-5 N·cm into plastic bosses; snug it up and stop.

No. Imperial look-alike: #0-80 UNF (1.52 mm) is the closest imperial screw, but it is bigger — not a substitute. Use a true M1.2 screw so it does not cross-thread or strip the hole.
