How to check the screw before you buy

  1. 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.
  2. Diameter: across the threads an M1.6 screw measures about 1.6 mm with calipers (usually a hair under). This device also uses M2 / M2.5 / M3, so measure each screw rather than assuming they match.
  3. Pitch: 0.35 mm from one thread crest to the next (28.57 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 1.7–25 mm, which means different positions take different lengths — match each hole to its own screw.
  6. Driver: the source does not name the drive. Standard M1.6 heads take PH00 for Phillips and T4–T5 for Torx, and a 1.5 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
  7. Tightening: no device-specific torque is published in these records. The site's general figure for M1.6 is about 12-20 N·cm into metal threads and 6-10 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M1.6 / M2 / M2.5 / M3

  • Headphone hinge screw sizes are usually quoted from screwdriver bit size, not an actual thread spec - measure before buying.
  • Xbox Series X internal chassis screws are M3, not M2 (confirmed on iFixit) — a widespread misconception.
  • Dell/HP/Lenovo manuals often list screws only by torque or head shape, so community teardowns are needed for diameter.
  • Part numbers can embed a thread code (e.g. ifm fibre fittings with 'M3') that refers to a fitting thread, not a chassis screw.

Questions about Lenovo ThinkPad 385 screws

What size screw does Lenovo ThinkPad 385 use?
M1.6 × 4 mm for screw kit (qty 2); M1.6 × 4 mm for unspecified (qty 2, flat, black); M2 × 1.7 mm for optical drive (qty 4); M2 × 10 mm for screw kit (qty 3); M2 × 10 mm for unspecified (qty 3, yellow); M2 × 14 mm for card reader (qty 2, yellow); M2 × 14 mm for screw kit (qty 5); M2 × 14 mm for unspecified (qty 1); M2 × 16 mm for unspecified (qty 2); M2 × 2.4 mm for optical drive (qty 4); M2 × 3.7 mm for display (qty 2); M2 × 3.7 mm for unspecified (qty 2, flat); M2 × 4 mm for hinge (qty 2); M2 × 4 mm for screw kit (qty 5); M2 × 4 mm for unspecified (qty 2); M2 × 4.3 mm for display (qty 2); M2 × 4.3 mm for display back cover (qty 6, flat); M2 × 4.3 mm for hinge (qty 4); M2 × 5 mm for display .
How long are the screws in Lenovo ThinkPad 385?
The records range from 1.7 to 25 mm depending on the position, so match each screw to its own hole.
What is the thread pitch of an M1.6 screw?
0.35 mm (coarse), which is the standard pitch for M1.6 machine screws; a 0.2 mm fine pitch exists but is uncommon. The tap drill is 1.25 mm and the normal clearance hole is 1.8 mm.
What screwdriver do I need for Lenovo ThinkPad 385?
The sources do not name the drive. For M1.6, Phillips heads normally take PH00 and Torx heads T4–T5; socket heads take a 1.5 mm hex key.
Can I use an imperial screw instead of M1.6?
No. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent. Use a true M1.6 screw so it does not cross-thread or strip the hole.
Where can I buy replacement screws for Lenovo ThinkPad 385?
TechSpareWarehouse (our own store) lists M1.6 x 4mm, M2 x 2.5mm and M2 x 4mm, which match lengths in the records above.
