NBK SSCZS pan-head captive miniature screw for precision instruments screw size
M1.2 · 4 to 10 mm long
NBK SSCZS pan-head captive miniature screw for precision instruments takes M1.2 metric screws in lengths from 4 to 10 mm.
The record covers NBK America miniature captive screw line marketed for precision instrument assemblies, available with M1.2/M1.4 nominal thread per manufacturer spec sheet.
This entry is marked confirmed and comes from alb02.internal.nbk1560.com.
For reference, M1.2 is 1.2 mm across the threads at 0.25 mm pitch. The imperial size people confuse it with: #0-80 UNF (1.52 mm) is the closest imperial screw, but it is bigger — not a substitute.

How to check the screw before you buy
- Keep material and finish the same as the original (often stainless) on equipment that is cleaned or sterilised.
- Diameter: across the threads an M1.2 screw measures about 1.2 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 0.25 mm from one thread crest to the next (40 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 M1.2 heads take PH000 / JIS 00 for Phillips and T1–T2 for Torx; 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 M1.2 is about 5-8 N·cm into metal threads and 3-5 N·cm into plastic bosses; snug it up and stop.
Common mix-ups with M1.2
- M1.2 and M1.4 look identical in an eyeglass repair kit — the wrong one strips soft acetate or metal hinges.

Questions about NBK SSCZS pan-head captive miniature screw for precision instruments screws
- What size screw does NBK SSCZS pan-head captive miniature screw for precision instruments use?
- M1.2 × 4–10 mm for NBK America miniature captive screw line marketed for precision instrument assemblies, available with M1.2/M1.4 nominal thread per manufacturer spec sheet.
- How long are the screws in NBK SSCZS pan-head captive miniature 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 M1.2 screw?
- 0.25 mm (coarse), which is the standard pitch for M1.2 machine screws. The tap drill is 0.95 mm and the normal clearance hole is 1.4 mm.
- What screwdriver do I need for NBK SSCZS pan-head captive miniature screw for precision instruments?
- The sources do not name the drive. For M1.2, Phillips heads normally take PH000 / JIS 00 and Torx heads T1–T2.
- Can I use an imperial screw instead of M1.2?
- No. Imperial look-alike: #0-80 UNF (1.52 mm) is the closest imperial screw, but it is bigger — not a substitute. Use a true M1.2 screw so it does not cross-thread or strip the hole.
