HP EliteBook 8460p screw size
M2 / M2.5 / M3 · 3 to 11 mm long
HP EliteBook 8460p takes M2, M2.5 and M3 metric screws in lengths from 3 to 11 mm.
There are 18 separate fitment records for it, including base cover (qty 2, pan, Phillips) (M2), card reader (qty 2, Phillips) (M2) and optical drive (qty 3, Phillips) (M2), plus 15 more in the table below.
Head and drive, as the sources state them: pan head and Phillips and Torx drives.
18 of the 18 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
- 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.
- 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.
- 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.
- Length: for pan head screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
- The records span 3–11 mm, which means different positions take different lengths — match each hole to its own screw.
- 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.
- 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.
- 3.5in desktop and enterprise hard drives are 6-32 UNC imperial, not M3 - only the 2.5in form factor is metric.

- M2 × 3 mm for base cover (qty 2, pan, Phillips); M2 × 3 mm for card reader (qty 2, Phillips); M2 × 3 mm for optical drive (qty 3, Phillips); M2 × 3 mm for system board (qty 2, Phillips); M2 × 3 mm for unspecified (qty 2, Phillips); M2 × 3 mm for wireless card (qty 2, Phillips); M2 × 4 mm for card reader (qty 1, broadhead, Phillips); M2 × 4 mm for display (qty 2, broadhead, Phillips); M2 × 4 mm for unspecified (qty 4, Phillips); M2 × 5 mm for speaker (qty 2, Phillips); M2.5 × 11 mm for base cover (qty 2, Phillips); M2.5 × 3 mm for hinge (qty 6, Phillips); M2.5 × 4 mm for system board (qty 2, Phillips); M2.5 × 4.5 mm for base cover (qty 2, Phillips); M2.5 × 4.5 mm for display (qty 2, Phillips).
- How long are the screws in HP EliteBook 8460p?
- The records range from 3 to 11 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 EliteBook 8460p?
- The source lists a Phillips and Torx 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 EliteBook 8460p?
- TechSpareWarehouse (our own store) lists M2 x 3mm, M2 x 4mm and M2 x 5mm, which match lengths in the records above.
