Eyeglass frame hinge/temple screws (industry standard) takes M1.2 metric screws, 8.7 mm long.
Where it is used: M1.2 thread, 2.0mm head, 8.7mm length small-head Phillips optical screw stocked as a standard eyewear repair size.
Head and drive, as the source states them: Phillips drive.
This entry is marked confirmed and comes from tabcooptical.com.
An M1.2 screw is 1.2 mm in diameter with a 0.25 mm pitch, tapped with a 0.95 mm drill; imperial look-alike: #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
- Do not confuse metric mounting screws with the 1/4-20 or 3/8-16 tripod threads that cameras and clamps also carry.
- 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 record states 8.7 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- Driver: the source names a Phillips drive. For comparison, standard M1.2 heads take PH000 / JIS 00 (Phillips) or T1–T2 (Torx).
- 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
- 'Universal' eyeglass kits mislabel diameter vs shaft: a listed 1.2 can measure 1.19-1.3mm between brands.
- M1.2 and M1.4 look identical in an eyeglass repair kit — the wrong one strips soft acetate or metal hinges.

Questions about Eyeglass frame hinge/temple screws (industry standard) screws
- What size screw does Eyeglass frame hinge/temple screws (industry standard) use?
- M1.2 × 8.7 mm for M1.2 thread, 2.0mm head, 8.7mm length small-head Phillips optical screw stocked as a standard eyewear repair size.
- How long are the screws in Eyeglass frame hinge/temple screws (industry standard)?
- The record gives 8.7 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- 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 Eyeglass frame hinge/temple screws (industry standard)?
- The source lists a Phillips drive. Standard M1.2 heads otherwise take PH000 / JIS 00 (Phillips) or T1–T2 (Torx).
- 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.
