Lenovo IdeaPad S10 screw size
M2 · 2.5 to 6 mm long
If you are replacing a screw on Lenovo IdeaPad S10, the thread is M2 in lengths from 2.5 to 6 mm.
There are 8 separate fitment records for it, including display (qty 4, wafer, silver) (M2), fan (qty 4, wafer, silver) (M2) and palm rest (qty 2, wafer, silver) (M2), plus 5 more in the table below.
Head and drive, as the sources state them: wafer (thin) head.
8 of the 8 records are marked confirmed, drawn from 1 source (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). If yours measures noticeably more or less, it is a different thread.
- 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 2.5–6 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 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
- 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).
- The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.

Questions about Lenovo IdeaPad S10 screws
- What size screw does Lenovo IdeaPad S10 use?
- M2 × 2.5 mm for display (qty 4, wafer, silver); M2 × 2.5 mm for fan (qty 4, wafer, silver); M2 × 2.5 mm for palm rest (qty 2, wafer, silver); M2 × 2.5 mm for wireless card (qty 2, wafer, silver); M2 × 4 mm for display (qty 4, wafer, silver); M2 × 4 mm for fan (qty 3, wafer, silver); M2 × 4 mm for palm rest (qty 2, wafer, silver); M2 × 6 mm for palm rest (qty 5, wafer, black).
- How long are the screws in Lenovo IdeaPad S10?
- The records range from 2.5 to 6 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 IdeaPad S10?
- 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 IdeaPad S10?
- TechSpareWarehouse (our own store) lists M2 x 2.5mm, M2 x 4mm and M2 x 6mm, which match lengths in the records above.
