HP Compaq 6715b screw size
M2 / M2.5 / M3 · 3 to 13 mm long
HP Compaq 6715b takes M2, M2.5 and M3 metric screws in lengths from 3 to 13 mm.
There are 23 separate fitment records for it, including hinge (qty 4, Phillips) (M2), optical drive (qty 2, black, Phillips) (M2) and hard drive (qty 2, black, Phillips) (M2), plus 20 more in the table below.
Head and drive, as the sources state them: Phillips and Torx T8 drives.
23 of the 23 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: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The records span 3–13 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
- 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.
- PC cases mix M3 (fans, optical and 2.5in drives) with imperial 6-32 (3.5in drives, motherboard standoffs) - don't force one into the other.

- How long are the screws in HP Compaq 6715b?
- The records range from 3 to 13 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 Compaq 6715b?
- The source lists a Phillips and Torx T8 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 Compaq 6715b?
- TechSpareWarehouse (our own store) lists M2 x 3mm, M2 x 5mm and M2 x 6mm, which match lengths in the records above.
