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: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads 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 names a Phillips drive. For comparison, standard M2 heads take PH0 (Phillips) or T6 (Torx), or a 1.5 mm hex key.
- 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).
- Dell/HP/Lenovo manuals often list screws only by torque or head shape, so community teardowns are needed for diameter.
- 3.5in desktop and enterprise hard drives are 6-32 UNC imperial, not M3 - only the 2.5in form factor is metric.

- How long are the screws in Lenovo G41-35?
- 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 G41-35?
- The source lists a Phillips drive. Standard M2 heads otherwise take PH0 (Phillips) or T6 (Torx), or 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 G41-35?
- TechSpareWarehouse (our own store) lists M2 x 2.5mm, M2 x 6mm and M2.5 x 4mm, which match lengths in the records above.
