There are 16 separate fitment records for it, including touchpad (qty 3, Phillips) (M1.6), system board (qty 6, Phillips) (M2) and speaker (qty 6, broadhead, Phillips) (M2), plus 13 more in the table below.

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

16 of the 16 records are marked confirmed, drawn from 1 source (kaas.hpcloud.hp.com).

M1.6 means a 1.6 mm nominal diameter with a 0.35 mm thread pitch. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent.

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 M1.6 screw measures about 1.6 mm with calipers (usually a hair under). This device also uses M2 / M2.5, so measure each screw rather than assuming they match.
  3. Pitch: 0.35 mm from one thread crest to the next (28.57 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 1.8–4.6 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 M1.6 heads take PH00 (Phillips) or T4–T5 (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 M1.6 is about 12-20 N·cm into metal threads and 6-10 N·cm into plastic bosses; snug it up and stop.

Common mix-ups with M1.6 / M2 / M2.5

  • Headphone hinge screw sizes are usually quoted from screwdriver bit size, not an actual thread spec - measure before buying.
  • 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.

How long are the screws in HP ProBook 460 G11?
The records range from 1.8 to 4.6 mm depending on the position, so match each screw to its own hole.
What is the thread pitch of an M1.6 screw?
0.35 mm (coarse), which is the standard pitch for M1.6 machine screws; a 0.2 mm fine pitch exists but is uncommon. The tap drill is 1.25 mm and the normal clearance hole is 1.8 mm.
What screwdriver do I need for HP ProBook 460 G11?
The source lists a Phillips drive. Standard M1.6 heads otherwise take PH00 (Phillips) or T4–T5 (Torx), or a 1.5 mm hex key.
Can I use an imperial screw instead of M1.6?
No. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent. Use a true M1.6 screw so it does not cross-thread or strip the hole.
Where can I buy replacement screws for HP ProBook 460 G11?
TechSpareWarehouse (our own store) lists M2 x 2mm, M2 x 2.5mm and M2 x 3mm, which match lengths in the records above.
