Small-head precision screw ('eyewire' screw stock, reused generically in tiny-device repair) screw size
M1.2 · 8.7 mm long
Our records put Small-head precision screw ('eyewire' screw stock, reused generically in tiny-device repair) on M1.2 screws, 8.7 mm long.
The record covers tabco Optical SM348 small-head Phillips screw. Page states verbatim: 'Thread M1.2 (1.2mm), Head 2.0mm diameter, Overall Length 8.7mm, Stainless Steel ... This screw is typical on smaller frames also called "Eyewire" screws.'.
Head and drive, as the source states them: Phillips drive.
This entry is marked reported 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
- VESA holes are threaded inserts in the back cover; if a screw stops early, back it out rather than forcing it, because a bottomed-out screw can crack the panel housing.
- 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 Small-head precision screw ('eyewire' screw stock, reused generically in tiny-device repair) screws
- What size screw does Small-head precision screw ('eyewire' screw stock, reused generically in tiny-device repair) use?
- M1.2 × 8.7 mm for tabco Optical SM348 small-head Phillips screw. Page states verbatim: 'Thread M1.2 (1.2mm), Head 2.0mm diameter, Overall Length 8.7mm, Stainless Steel ... This screw is typical on smaller frames also called "Eyewire" screws.'.
- How long are the screws in Small-head precision screw ('eyewire' screw stock, reused generically in tiny-device repair)?
- 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 Small-head precision screw ('eyewire' screw stock, reused generically in tiny-device repair)?
- 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.
