HP ZBook 8 G1ah 14 inch screw size
M1.6 / M2 / M2.5 · 2 to 5 mm long
HP ZBook 8 G1ah 14 inch takes M1.6, M2 and M2.5 metric screws in lengths from 2 to 5 mm.
There are 9 separate fitment records for it, including touchpad (qty 7, Phillips) (M1.6), card reader (qty 3, Phillips) (M2) and power button (qty 1, Phillips) (M2), plus 6 more in the table below.
Head and drive, as the sources state them: Phillips drive.
9 of the 9 records are marked confirmed, drawn from 1 source (kaas.hpcloud.hp.com).
For reference, M1.6 is 1.6 mm across the threads at 0.35 mm pitch. The imperial size people confuse it with: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent.

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 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.
- 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.
- Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The records span 2–5 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 M1.6 heads take PH00 (Phillips) or T4–T5 (Torx), or a 1.5 mm hex key.
- 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
- 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.

- How long are the screws in HP ZBook 8 G1ah 14 inch?
- The records range from 2 to 5 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 ZBook 8 G1ah 14 inch?
- 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 ZBook 8 G1ah 14 inch?
- TechSpareWarehouse (our own store) lists M2 x 2mm, M2 x 2.5mm and M2 x 4mm, which match lengths in the records above.
