JIS/ISO metric camera and lens internal screws (JCIS #0 driver family) screw size
M1.4 · length not stated in the sources
The screws used on JIS/ISO metric camera and lens internal screws (JCIS #0 driver family) are M1.4. None of the sources we found gives an exact length, so measure the original before you order.
The record covers precision JIS HSS-E tap & drill set advertised specifically as 'M1.4 x 0.30mm' for camera and lens repair taps, and referencing JCIS-standard camera screws being metric-threaded.
Head and drive, as the source states them: Phillips drive.
This entry is marked reported and comes from polarbearcamera.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
- Camera and optics hardware often uses short screws into thin threaded plates, so check engagement before tightening fully.
- Diameter: across the threads an M1.4 screw measures about 1.4 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- 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.
- Driver: the source names a Phillips drive. For comparison, standard M1.4 heads take PH000 / PH00 (Phillips) or T2–T3 (Torx), or a 1.3 mm hex key.
- 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
- Whoop drone M1.4 comes in steel, PEEK and RENY versions: plastic ones are for cameras, not structural frame use.
- Slice Engineering also lists 1.3mm and 2mm hex keys - those are driver sizes, not thread sizes.

Questions about JIS/ISO metric camera and lens internal screws (JCIS #0 driver family) screws
- What size screw does JIS/ISO metric camera and lens internal screws (JCIS #0 driver family) use?
- M1.4 for precision JIS HSS-E tap & drill set advertised specifically as 'M1.4 x 0.30mm' for camera and lens repair taps, and referencing JCIS-standard camera screws being metric-threaded.
- How long are the screws in JIS/ISO metric camera and lens internal screws (JCIS #0 driver family)?
- None of the sources states a length. Remove one screw and measure it from under the head to the tip (overall for a countersunk head).
- 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 JIS/ISO metric camera and lens internal screws (JCIS #0 driver family)?
- The source lists a Phillips drive. Standard M1.4 heads otherwise take PH000 / PH00 (Phillips) or T2–T3 (Torx), or 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.
