HP 510 screw size

M2 / M2.5 / M3 · 2 to 9 mm long

If you are replacing a screw on HP 510, the thread is M2, M2.5 and M3 in lengths from 2 to 9 mm.

There are 24 separate fitment records for it, including unspecified (qty 7, Phillips) (M2), card reader (qty 2, Phillips) (M2) and hinge (qty 4, Phillips) (M2), plus 21 more in the table below.

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

24 of the 24 records are marked confirmed, drawn from 1 source (tim.id.au).

M2 means a 2 mm nominal diameter with a 0.4 mm thread pitch. Imperial look-alike: #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 / M3, 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 2–9 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 / M3

  • The standard M.2 SSD screw is M2 x 3mm, but some laptops and handhelds use non-standard lengths or head shapes.
  • M2.5 pitch is 0.45mm vs M3's 0.5mm and M2's 0.4mm — forcing the wrong one strips plastic bosses instantly.
  • PC cases mix M3 (fans, optical and 2.5in drives) with imperial 6-32 (3.5in drives, motherboard standoffs) - don't force one into the other.

Questions about HP 510 screws

What size screw does HP 510 use?
M2 × 2 mm for unspecified (qty 7, Phillips); M2 × 3 mm for card reader (qty 2, Phillips); M2 × 3 mm for hinge (qty 4, Phillips); M2 × 3 mm for memory (qty 89, Phillips); M2 × 3 mm for optical drive (qty 2, Phillips); M2 × 3 mm for system board (Phillips); M2 × 3 mm for unspecified (qty 2, Phillips); M2 × 7 mm for display (qty 2, Phillips); M2 × 7 mm for unspecified (qty 91, Phillips); M2 × 9 mm for display (qty 2, Phillips); M2 × 9 mm for fan (Phillips); M2 × 9 mm for keyboard (qty 2, Phillips); M2 × 9 mm for memory (qty 85, Phillips); M2 × 9 mm for optical drive (Phillips); M2 × 9 mm for speaker (Phillips); M2 × 9 mm for unspecified (qty 7, Phillips); M2.5 × 4 mm for display (Phillips); M2..
How long are the screws in HP 510?
The records range from 2 to 9 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 510?
The source lists a Phillips 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 510?
TechSpareWarehouse (our own store) lists M2 x 2mm, M2 x 3mm and M2.5 x 4mm, which match lengths in the records above.
