Precision instrument hex socket head screws screw size
M2 · 2 to 12 mm long
If you are replacing a screw on Precision instrument hex socket head screws, the thread is M2 in lengths from 2 to 12 mm.
Where it is used: NBK SNSS miniature screw catalog explicitly lists M2 as a selectable coarse thread nominal alongside M1, M1.4, M1.6, M2.5.
This entry is marked confirmed and comes from alb02.internal.nbk1560.com.
An M2 screw is 2 mm in diameter with a 0.4 mm pitch, tapped with a 1.6 mm drill; imperial look-alike: #2-56 UNC (2.18 mm) is close but not interchangeable.

How to check the screw before you buy
- Instrument and audio hardware often threads into wood or thin metal; a screw that is too long can poke through a finished surface.
- Diameter: across the threads an M2 screw measures about 2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- 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 2–12 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M2 heads take PH0 for Phillips and T6 for Torx, and a 1.5 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
- 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' is sometimes used loosely by resellers to mean 'roughly 2mm' without a real ISO metric thread; only counted here when the source datasheet explicitly states 'M2' thread.
- M2 (2.00mm, 0.4mm pitch) is NOT the same as #2-56 UNC (2.18mm) — close enough to cross-thread and strip if forced.

Questions about Precision instrument hex socket head screws screws
- What size screw does Precision instrument hex socket head screws use?
- M2 × 2–12 mm for NBK SNSS miniature screw catalog explicitly lists M2 as a selectable coarse thread nominal alongside M1, M1.4, M1.6, M2.5.
- How long are the screws in Precision instrument hex socket head screws?
- The records range from 2 to 12 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 Precision instrument hex socket head screws?
- The sources do not name the drive. For M2, Phillips heads normally take PH0 and Torx heads T6; socket heads take 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.
