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, 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 2–7 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 M1.6 heads take PH00 (Phillips) or T4–T5 (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 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

  • 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).
  • M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.

What size screw does HP Spectre x360 14 inch 2-in-1 use?
M1.6 × 2 mm for SSD (qty 1, Phillips); M1.6 × 2 mm for touchpad (qty 14, Phillips); M1.6 × 3 mm for speaker (qty 4, Phillips); M2 × 2 mm for hinge (qty 3, broadhead, Phillips); M2 × 2.5 mm for SSD (qty 3, Phillips); M2 × 2.5 mm for wireless card (qty 1, Phillips); M2 × 3.5 mm for I/O board (qty 1, Phillips); M2 × 3.5 mm for battery (qty 5, Phillips); M2 × 3.5 mm for bracket (qty 2, Phillips); M2 × 3.5 mm for power button (qty 7, Phillips); M2 × 3.5 mm for system board (qty 5, Phillips); M2 × 3.5 mm for unspecified (qty 1, Phillips); M2 × 4 mm for base cover (qty 2, Phillips); M2 × 7 mm for base cover (qty 2, Phillips); M2.5 × 5 mm for display (qty 4, Phillips).
How long are the screws in HP Spectre x360 14 inch 2-in-1?
The records range from 2 to 7 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 HP Spectre x360 14 inch 2-in-1?
The source lists a Phillips drive. Standard M1.6 heads otherwise take PH00 (Phillips) or T4–T5 (Torx), or 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 HP Spectre x360 14 inch 2-in-1?
TechSpareWarehouse (our own store) lists M1.6 x 3mm, M2 x 2mm and M2 x 2.5mm, which match lengths in the records above.
