HP nx6125 PCs screw size
M2.5 / M3 · 4 to 9 mm long
HP nx6125 PCs takes M2.5 and M3 metric screws in lengths from 4 to 9 mm.
There are 19 separate fitment records for it, including LED board (qty 1, Torx T8) (M2.5), keyboard (qty 4, black, Torx T8) (M2.5) and optical drive (qty 3, Torx T8) (M2.5), plus 16 more in the table below.
Head and drive, as the sources state them: Torx T8 and Phillips drives.
19 of the 19 records are marked confirmed, drawn from 1 source (h10032.www1.hp.com).
For reference, M2.5 is 2.5 mm across the threads at 0.45 mm pitch. The imperial size people confuse it with: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in.

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 M2.5 screw measures about 2.5 mm with calipers (usually a hair under). This device also uses M3, so measure each screw rather than assuming they match.
- Pitch: 0.45 mm from one thread crest to the next (22.22 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 4–9 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Torx T8 drive. For comparison, standard M2.5 heads take PH1 (Phillips) or T8 (Torx), or a 2 mm hex key.
- Tightening: no device-specific torque is published in these records. The site's general figure for M2.5 is about 45-70 N·cm into metal threads and 20-35 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M2.5 / M3
- M2.5 and M3 look the same to the naked eye — you need calipers on the shank to tell them apart.
- M2.5 pitch is 0.45mm vs M3's 0.5mm and M2's 0.4mm — forcing the wrong one strips plastic bosses instantly.
- LED strip clips strip easily — M3x12 into thin plastic should be hand-driven, never with a power driver.
- 3.5in desktop and enterprise hard drives are 6-32 UNC imperial, not M3 - only the 2.5in form factor is metric.

- How long are the screws in HP nx6125 PCs?
- The records range from 4 to 9 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M2.5 screw?
- 0.45 mm (coarse), which is the standard pitch for M2.5 machine screws; a 0.35 mm fine pitch exists but is uncommon. The tap drill is 2.05 mm and the normal clearance hole is 2.9 mm.
- What screwdriver do I need for HP nx6125 PCs?
- The source lists a Torx T8 and Phillips drive. Standard M2.5 heads otherwise take PH1 (Phillips) or T8 (Torx), or a 2 mm hex key.
- Can I use an imperial screw instead of M2.5?
- No. Imperial look-alike: #3-48 / #4-40 (2.51 / 2.84 mm) — #4-40 is the common US stand-in and it will NOT thread in. Use a true M2.5 screw so it does not cross-thread or strip the hole.
