HP Spectre x360 15 screw size

M2 / M2.5 · 2 to 10 mm long

HP Spectre x360 15 takes M2 and M2.5 metric screws in lengths from 2 to 10 mm.

There are 34 separate fitment records for it, including base cover (qty 6, Phillips) (M2), heat sink (qty 6, Phillips) (M2) and speaker (qty 2, Phillips) (M2), plus 31 more in the table below.

Head and drive, as the sources state them: Phillips and Torx T5 drives.

34 of the 34 records are marked confirmed, drawn from 2 sources (h10032.www1.hp.com and kaas.hpcloud.hp.com).

For reference, M2 is 2 mm across the threads at 0.4 mm pitch. The imperial size people confuse it with: #2-56 UNC (2.18 mm) is close but not interchangeable.

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 M2 screw measures about 2 mm with calipers (usually a hair under). This device also uses M2.5, 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 2–10 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

  • 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).
  • The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.
  • M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.
  • M2.5 pitch is 0.45mm vs M3's 0.5mm and M2's 0.4mm — forcing the wrong one strips plastic bosses instantly.

Questions about HP Spectre x360 15 screws

What size screw does HP Spectre x360 15 use?
M2 × 10 mm for base cover (qty 6, Phillips); M2 × 2 mm for heat sink (qty 6, Phillips); M2 × 2 mm for speaker (qty 2, Phillips); M2 × 2 mm for touchpad (qty 3, Phillips); M2 × 2.2 mm for touchpad (qty 3, Phillips); M2 × 2.5 mm for memory (qty 1, Phillips); M2 × 2.5 mm for power button (qty 1, Phillips); M2 × 2.5 mm for SSD (qty 1, Phillips); M2 × 2.5 mm for wireless card (qty 1, Phillips); M2 × 2.6 mm for speaker (qty 2, broadhead, Phillips); M2 × 2.6 mm for system board (qty 2, broadhead, Phillips); M2 × 2.6 mm for unspecified (qty 1, broadhead, Phillips); M2 × 3.2 mm for SSD (qty 1, Phillips); M2 × 3.5 mm for I/O board (qty 1, Phillips); M2 × 3.5 mm for base cover (qty 2, Phillips); M2 × 3.
How long are the screws in HP Spectre x360 15?
The records range from 2 to 10 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 HP Spectre x360 15?
The source lists a Phillips and Torx T5 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 HP Spectre x360 15?
TechSpareWarehouse (our own store) lists M2 x 2mm, M2 x 2.5mm and M2 x 3mm, which match lengths in the records above.
