Lenovo ThinkPad X41 screw size
M2 / M2.5 / M3 · 2.5 to 8 mm long
If you are replacing a screw on Lenovo ThinkPad X41, the thread is M2, M2.5 and M3 in lengths from 2.5 to 8 mm.
There are 29 separate fitment records for it, including display bezel (qty 6) (M2), hinge (qty 2) (M2) and unspecified (qty 2, wafer, silver) (M2), plus 26 more in the table below.
Head and drive, as the sources state them: wafer (thin) head.
29 of the 29 records are marked confirmed, drawn from 2 sources (thinkpad-manuals.retropc.se and tim.id.au).
For reference, M2 is 2 mm across the threads at 0.4 mm pitch. The imperial size people confuse it with: #2-56 UNC (2.18 mm) is close but not interchangeable.

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 M2 screw measures about 2 mm with calipers (usually a hair under). This device also uses M2.5 / M3, so measure each screw rather than assuming they match.
- Pitch: 0.4 mm from one thread crest to the next (25 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 2.5–8 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 heads take PH0 for Phillips and T6 for Torx, and a 1.5 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 is about 25-40 N·cm into metal threads and 12-20 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2 / M2.5 / M3
- M.2 SSD mounting screws (M2 x 3mm) are frequently mislabeled generically as 'M.2 screws' which can be confused with the M2 metric thread designation — they do coincide numerically here but are conceptually distinct (M.2 = card format, M2 = thread size).
- Nylon-coated M2.5 screws (ThinkPad Edge) are thread-locking; plain replacements work loose over time.
- Power-tool gearcase and clamshell screws are usually thread-forming (marked "ST") even when the parts list gives an M-size — a normal machine screw of the same size may not hold in the plastic boss.

Questions about Lenovo ThinkPad X41 screws
- What size screw does Lenovo ThinkPad X41 use?
- M2 × 2.5 mm for display bezel (qty 6); M2 × 2.5 mm for hinge (qty 2); M2 × 2.5 mm for unspecified (qty 2, wafer, silver); M2 × 2.5 mm for wireless card (qty 2); M2 × 3 mm for memory (qty 3, wafer, black); M2 × 3.5 mm for base cover (qty 2); M2 × 3.5 mm for display (qty 4, wafer, silver); M2 × 3.5 mm for fan (qty 2); M2 × 3.5 mm for hard drive (qty 2, wafer, silver); M2 × 3.5 mm for palm rest (qty 4, wafer, silver); M2 × 3.5 mm for power button (qty 2); M2 × 3.5 mm for system board (qty 2, wafer, silver); M2 × 3.5 mm for unspecified (qty 3, wafer, silver); M2 × 3.5 mm for wireless card (qty 2, wafer, silver); M2 × 6 mm for base cover (qty 2); M2 × 6 mm for display (qty 4); M2 × 6 mm for keybo.
- How long are the screws in Lenovo ThinkPad X41?
- The records range from 2.5 to 8 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M2 screw?
- 0.4 mm (coarse), which is the standard pitch for M2 machine screws; a 0.25 mm fine pitch exists but is uncommon. The tap drill is 1.6 mm and the normal clearance hole is 2.4 mm.
- What screwdriver do I need for Lenovo ThinkPad X41?
- The sources do not name the drive. For M2, Phillips heads normally take PH0 and Torx heads T6; socket heads take a 1.5 mm hex key.
- Can I use an imperial screw instead of M2?
- No. Imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable. Use a true M2 screw so it does not cross-thread or strip the hole.
- Where can I buy replacement screws for Lenovo ThinkPad X41?
- TechSpareWarehouse (our own store) lists M2 x 2.5mm, M2 x 3mm and M2 x 6mm, which match lengths in the records above.
