Lenovo ThinkPad X1 Nano Gen 2 screw size
M1.2 / M1.6 / M2 / M2.5 · 1.8 to 4.5 mm long
Lenovo ThinkPad X1 Nano Gen 2 takes M1.2, M1.6, M2 and M2.5 metric screws in lengths from 1.8 to 4.5 mm.
There are 5 separate fitment records for it, including screw-kit fastener, red coded (qty 6) (M1.2), base cover flat-head nylon-coated screws (M1.6) and bottom cover and chassis screws, several lengths (M2), plus 2 more in the table below.
Head and drive, as the sources state them: flat / countersunk head.
5 of the 5 records are marked confirmed, drawn from 2 sources (ThinkPad X1 Nano Gen 2 Hardware Maintenance Manual and ThinkPad X1 Nano Gen 2 HMM).
An M1.2 screw is 1.2 mm in diameter with a 0.25 mm pitch, tapped with a 0.95 mm drill; imperial look-alike: #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
- 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.
- 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: the source describes a countersunk (flat) head, and those are measured overall, from the top of the head to the tip.
- The records span 1.8–4.5 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M1.2 heads take PH000 / JIS 00 for Phillips and T1–T2 for Torx; 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 M1.2 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
- Framework lists both M1.2 x 3.0 silver and M1.6 x 3.0 black expansion-card screws; they look identical in the tray but are not interchangeable.
- Xbox Series X internal chassis screws are M3, not M2 (confirmed on iFixit) — a widespread misconception.
- Nylon-coated M2.5 screws (ThinkPad Edge) are thread-locking; plain replacements work loose over time.

- What screwdriver do I need for Lenovo ThinkPad X1 Nano Gen 2?
- The sources do not name the drive. For M1.2, Phillips heads normally take PH000 / JIS 00 and Torx heads T1–T2.
