NBK SSCZS miniature captive screw for precision instruments screw size
M1.4 / M1.6 / M2.5 · 4 to 10 mm long
The screws used on NBK SSCZS miniature captive screw for precision instruments are M1.4, M1.6 and M2.5 in lengths from 4 to 10 mm.
There are 3 separate fitment records for it, including NBK America miniature/micro screw line explicitly offers M1.4 nominal coarse thread option (M1.4), M1.6 nominal thread offered within NBK SSCZS miniature captive screw range for precision-i (M1.6) and M2.5 nominal thread offered in NBK's SSCZS miniature captive-screw line for precision inst (M2.5).
3 of the 3 records are marked confirmed, drawn from 1 source (alb02.internal.nbk1560.com).
For reference, M1.4 is 1.4 mm across the threads at 0.3 mm pitch. The imperial size people confuse it with: #0-80 UNF (1.52 mm) — close in diameter, different pitch, do not mix.

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 M1.4 screw measures about 1.4 mm with calipers (usually a hair under). This device also uses M1.6 / M2.5, so measure each screw rather than assuming they match.
- Pitch: 0.3 mm from one thread crest to the next (33.33 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 4–10 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M1.4 heads take PH000 / PH00 for Phillips and T2–T3 for Torx, and a 1.3 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 M1.4 is about 8-12 N·cm into metal threads and 4-7 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M1.4 / M1.6 / M2.5
- Dental implant screws (M1.4/M1.6) are proprietary per system — Bredent, NeoBiotech, Nobel and Straumann are not interchangeable even at the same nominal size.
- M1.6 is the most common laptop-internal micro screw after M2 — Dell XPS keyboards specifically call out M1.6 x 1.5mm, and generic M2 substitutes strip the bracket.
- Commonly confused with imperial 4-40 screws in older medical equipment, but modern GE/Mindray devices explicitly list M2.5 metric threads.

Questions about NBK SSCZS miniature captive screw for precision instruments screws
- What size screw does NBK SSCZS miniature captive screw for precision instruments use?
- M1.4 × 4–10 mm for NBK America miniature/micro screw line explicitly offers M1.4 nominal coarse thread option (SSCZS-M1.4) for precision-instrument captive screw applications; M1.6 × 4–10 mm for M1.6 nominal thread offered within NBK SSCZS miniature captive screw range for precision-instrument assemblies; M2.5 × 4–10 mm for M2.5 nominal thread offered in NBK's SSCZS miniature captive-screw line for precision instrument assemblies.
- How long are the screws in NBK SSCZS miniature captive screw for precision instruments?
- The records range from 4 to 10 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M1.4 screw?
- 0.3 mm (coarse), which is the standard pitch for M1.4 machine screws. The tap drill is 1.1 mm and the normal clearance hole is 1.6 mm.
- What screwdriver do I need for NBK SSCZS miniature captive screw for precision instruments?
- The sources do not name the drive. For M1.4, Phillips heads normally take PH000 / PH00 and Torx heads T2–T3; socket heads take a 1.3 mm hex key.
- Can I use an imperial screw instead of M1.4?
- No. Imperial look-alike: #0-80 UNF (1.52 mm) — close in diameter, different pitch, do not mix. Use a true M1.4 screw so it does not cross-thread or strip the hole.
- Where can I buy replacement screws for NBK SSCZS miniature captive screw for precision instruments?
- TechSpareWarehouse (our own store) lists M1.6 x 4mm, M2.5 x 4mm and M2.5 x 5mm, which match lengths in the records above.
