HP Compaq nc4010 screw size

M2 / M2.5 · 3 to 10 mm long

If you are replacing a screw on HP Compaq nc4010, the thread is M2 and M2.5 in lengths from 3 to 10 mm.

There are 25 separate fitment records for it, including hard drive (qty 2) (M2), heat sink (qty 2, captive, silver, Torx T8) (M2) and fan (qty 3, silver, Phillips) (M2), plus 22 more in the table below.

Head and drive, as the sources state them: shoulder screw head and Torx T8, Phillips and Torx T5 drives.

25 of the 25 records are marked confirmed, drawn from 1 source (h10032.www1.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. 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, 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: for shoulder screw screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
  5. The records span 3–10 mm, which means different positions take different lengths — match each hole to its own screw.
  6. Driver: the source names a Torx T8 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

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

Questions about HP Compaq nc4010 screws

What size screw does HP Compaq nc4010 use?
M2 × 10 mm for hard drive (qty 2); M2 × 10 mm for heat sink (qty 2, captive, silver, Torx T8); M2 × 3 mm for fan (qty 3, silver, Phillips); M2 × 3 mm for hard drive (qty 2, black, Phillips); M2 × 3 mm for unspecified (qty 2, silver, Phillips); M2 × 4 mm for heat sink (qty 4, black, Torx T8); M2 × 4 mm for memory (qty 1, black, Phillips); M2 × 4 mm for palm rest (qty 5, black); M2 × 4 mm for speaker (qty 2, black, Phillips); M2 × 4 mm for system board (qty 3, black); M2 × 4 mm for touchpad (qty 2, black, Phillips); M2 × 4 mm for unspecified (qty 1, Torx T8); M2 × 4 mm for wireless card (qty 4, black, Phillips,Torx T8); M2 × 6 mm for system board (qty 2, black); M2 × 6 mm for unspecified (qty .
How long are the screws in HP Compaq nc4010?
The records range from 3 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 Compaq nc4010?
The source lists a Torx T8, 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 Compaq nc4010?
TechSpareWarehouse (our own store) lists M2 x 3mm, M2 x 4mm and M2 x 6mm, which match lengths in the records above.
