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 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: for shoulder screw / wafer (thin) head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
  5. The records span 2–8 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.
  • 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.
  • 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 ThinkPad X200 Tablet screws

What size screw does Lenovo ThinkPad X200 Tablet use?
M1.6 × 3 mm for DC-in (qty 1, shoulder, black); M2 × 2 mm for display (qty 4, wafer, black); M2 × 2 mm for palm rest (qty 1, wafer, black); M2 × 3 mm for display (qty 6, flat, black); M2 × 3 mm for unspecified (qty 5, flat, black); M2 × 3.5 mm for camera (qty 1, wafer, silver); M2 × 3.5 mm for DC-in (qty 6, wafer,flat, silver,black); M2 × 3.5 mm for display (qty 5, wafer, silver); M2 × 3.5 mm for display back cover (qty 3, wafer, silver); M2 × 3.5 mm for memory (qty 2, wafer, silver); M2 × 3.5 mm for palm rest (qty 4, wafer, silver); M2 × 3.5 mm for system board (qty 1, wafer, silver); M2 × 3.5 mm for unspecified (qty 3, wafer, silver); M2 × 3.5 mm for wireless card (qty 2, wafer, silver); M.
How long are the screws in Lenovo ThinkPad X200 Tablet?
The records range from 2 to 8 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 X200 Tablet?
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 X200 Tablet?
TechSpareWarehouse (our own store) lists M1.6 x 3mm, M2 x 2mm and M2 x 3mm, which match lengths in the records above.
