How to check the screw before you buy

  1. 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).
  2. 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.
  3. 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.
  4. Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
  5. The records span 2–6 mm, which means different positions take different lengths — match each hole to its own screw.
  6. 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.
  7. 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.

Questions about Lenovo E41-15 screws

What size screw does Lenovo E41-15 use?
M2 × 2 mm for base cover (qty 2, flat, black); M2 × 3 mm for display (qty 4, flat, black); M2 × 3 mm for fan (qty 3, black, Phillips); M2 × 3 mm for system board (qty 2, flat, black); M2 × 3 mm for wireless card (qty 1, flat, black); M2 × 4 mm for hard drive (qty 3, flat, silver); M2 × 4 mm for speaker (qty 1, flat, silver); M2 × 5 mm for battery (qty 2, flat, silver); M2 × 5 mm for fan (qty 1, silver, Phillips); M2.5 × 2.5 mm for display (qty 6, flat, black); M2.5 × 6 mm for base cover (qty 8, flat, black); M2.5 × 6 mm for display (qty 5, flat, black); M2.5 × 6 mm for keyboard (qty 3, flat, black); M3 × 3 mm for hard drive (qty 4, flat, silver).
How long are the screws in Lenovo E41-15?
The records range from 2 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 E41-15?
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 E41-15?
TechSpareWarehouse (our own store) lists M2 x 2mm, M2 x 3mm and M2 x 4mm, which match lengths in the records above.
