Dell XPS 13 9310 2-in-1 screw size
M1.2 / M1.6 / M2 / M2.5 · 1.4 to 4.5 mm long
The screws used on Dell XPS 13 9310 2-in-1 are M1.2, M1.6, M2 and M2.5 in lengths from 1.4 to 4.5 mm.
There are 16 separate fitment records for it, including keyboard (qty 38) (M1.2), keyboard (qty 10) (M1.2) and keyboard (qty 1, captive) (M1.2), plus 13 more in the table below.
Head and drive, as the sources state them: Torx T5 and Torx drives.
16 of the 16 records are marked confirmed, drawn from 1 source (dl.dell.com).
For reference, M1.2 is 1.2 mm across the threads at 0.25 mm pitch. The imperial size people confuse it with: #0-80 UNF (1.52 mm) is the closest imperial screw, but it is bigger — not a substitute.

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 M1.2 screw measures about 1.2 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: 0.25 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.
- 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 1.4–4.5 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 M1.2 heads take PH000 / JIS 00 (Phillips) or T1–T2 (Torx).
- 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.
Common mix-ups with M1.2 / M1.6 / M2 / M2.5
- M1.2 and M1.4 look identical in an eyeglass repair kit — the wrong one strips soft acetate or metal hinges.
- 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.

- 0.25 mm (coarse), which is the standard pitch for M1.2 machine screws. The tap drill is 0.95 mm and the normal clearance hole is 1.4 mm.
