Lenovo ThinkPad T / X / L series screw size
M2.5 · 3 to 6 mm long
Lenovo ThinkPad T / X / L series takes M2.5 metric screws in lengths from 3 to 6 mm.
The record covers palmrest-to-base and hinge bracket screws, black oxide flat/wafer head.
Head and drive, as the source states them: wafer (thin) head.
This entry is marked reported and comes from support.lenovo.com.
For reference, M2.5 is 2.5 mm across the threads at 0.45 mm pitch. The imperial size people confuse it with: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in.

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 M2.5 screw measures about 2.5 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.45 mm from one thread crest to the next (22.22 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: for wafer (thin) head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The records span 3–6 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M2.5 heads take PH1 for Phillips and T8 for Torx, and a 2 mm hex key for socket heads; 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 M2.5 is about 45-70 N·cm into metal threads and 20-35 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2.5
- Nylon-coated M2.5 screws (ThinkPad Edge) are thread-locking; plain replacements work loose over time.
- Dell/HP/Lenovo manuals often list screws only by torque or head shape, so community teardowns are needed for diameter.
