HP 2000 screw size

M2 / M2.5 / M3 · 2.8 to 8 mm long

If you are replacing a screw on HP 2000, the thread is M2, M2.5 and M3 in lengths from 2.8 to 8 mm.

There are 19 separate fitment records for it, including I/O board (qty 2, Phillips) (M2), battery (qty 4, Phillips) (M2) and card reader (qty 1, Phillips) (M2), plus 16 more in the table below.

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

19 of the 19 records are marked confirmed, drawn from 1 source (kaas.hpcloud.hp.com).

An M2 screw is 2 mm in diameter with a 0.4 mm pitch, tapped with a 1.6 mm drill; 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 2.8–8 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

  • 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.
  • Power-tool gearcase and clamshell screws are usually thread-forming (marked "ST") even when the parts list gives an M-size — a normal machine screw of the same size may not hold in the plastic boss.

Questions about HP 2000 screws

What size screw does HP 2000 use?
M2 × 2.8 mm for I/O board (qty 2, Phillips); M2 × 2.8 mm for battery (qty 4, Phillips); M2 × 2.8 mm for card reader (qty 1, Phillips); M2 × 2.8 mm for hard drive (qty 3, Phillips); M2 × 2.8 mm for heat sink (qty 6, Phillips); M2 × 2.8 mm for hinge (qty 1, Phillips); M2 × 2.8 mm for power button (qty 1, Phillips); M2 × 2.8 mm for SSD (qty 3, Phillips); M2 × 2.8 mm for system board (qty 3, Phillips); M2 × 2.8 mm for touchpad (qty 2, Phillips); M2 × 3 mm for memory (qty 1, Phillips); M2 × 3 mm for SSD (qty 1, Phillips); M2 × 3 mm for wireless card (qty 1, Phillips); M2 × 4 mm for base cover (qty 2, Phillips); M2 × 4 mm for fan (qty 1, Phillips); M2.5 × 3.5 mm for hinge (qty 3, Phillips); M2.5 ×.
How long are the screws in HP 2000?
The records range from 2.8 to 8 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 2000?
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 2000?
TechSpareWarehouse (our own store) lists M2 x 3mm, M2 x 4mm and M2.5 x 6mm, which match lengths in the records above.
