Lenovo ThinkPad T14s Gen 3 screw size
M1.2 / M1.6 / M2 / M2.5 · 1.7 to 5 mm long
If you are replacing a screw on Lenovo ThinkPad T14s Gen 3, the thread is M1.2, M1.6, M2 and M2.5 in lengths from 1.7 to 5 mm.
There are 8 separate fitment records for it, including service screw kit, most common small screw (47x) (M1.2), service screw kit (14x) (M1.2) and service screw kit (13x) (M1.6), plus 5 more in the table below.
Head and drive, as the sources state them: flat / countersunk head.
8 of the 8 records are marked confirmed, drawn from 1 source (download.lenovo.com).
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
- 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: the source describes a countersunk (flat) head, and those are measured overall, from the top of the head to the tip.
- The records span 1.7–5 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.
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.
- Headphone hinge screw sizes are usually quoted from screwdriver bit size, not an actual thread spec - measure before buying.
- The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.
- Nylon-coated M2.5 screws (ThinkPad Edge) are thread-locking; plain replacements work loose over time.

- The sources do not name the drive. For M1.2, Phillips heads normally take PH000 / JIS 00 and Torx heads T1–T2.
- Can I use an imperial screw instead of M1.2?
