Head styles & standards cross-reference
- Socket cap (cylindrical head)ISO 4762 / DIN 912M1.2 socket cap, the default engineering hex-drive screw
- Low-head socket capDIN 7984 / ISO 7380-style low profileReduced head height — the usual choice where a standard cap head would foul
- Button headISO 7380-1Domed low head, common on 3D printers, cages and brackets
- Countersunk (flat) socketISO 10642 / DIN 799190° head, sits flush in a chamfered hole
- Pan head PhillipsISO 7045 / DIN 7985 (JIS B 1111 in Japanese gear)Most consumer-electronics service screws are this family
- Countersunk PhillipsISO 7046 / DIN 965Flush pan-equivalent for plastics and covers
- Pan / countersunk TorxISO 14583 / ISO 14581Used where higher torque or tamper resistance is needed
Supplier part numbers
Fastener suppliers build codes from style + size + length + material rather than a single universal number. These are the patterns to search with.

- AccuSSC-M1.2-6-A2 (socket cap), SPP-M1.2-6-A2 (pan Phillips)Accu part codes are built as style-thread-length-material
- Bossard / WürthISO 4762 M1.2x6 A2-70European distributors order by standard + size + material grade, not a fixed SKU

Watch out for
- M1.2 and M1.4 look identical in an eyeglass repair kit — the wrong one strips soft acetate or metal hinges.
- 'Universal' eyeglass kits mislabel diameter vs shaft: a listed 1.2 can measure 1.19-1.3mm between brands.
- Phone makers rarely specify M1.2 by part number — M1.4 is far more common in smartphones.
- Anbernic RG35XX rear screws need a 1.5mm hex bit — a small Phillips will not fit (https://www.ifixit.com/Guide/Anbernic+RG35XX+Rear+Case+Replacement/180641)
- Apple never publishes pentalobe thread specs — M1.2 figures come from caliper measurements posted in forums.
- Driver size is not thread size: Steam Deck's eight screw types span M1.2 to M2 while sharing similar drive heads.
- Official Sony/Canon/Nikon/Fujifilm service manuals and OEM screw part listings found in this research (ManualsLib service manuals, Canon genuine screw SKUs like CA2-4586/YA2-8001-000) list part numbers and driver types but do not publicly state metric thread callouts on the pages actually accessible; only third-party forum measurements (mflenses) provided explicit metric sizes for lens-mount screws, so OEM-confirmed entries for these brands could not be included under the strict-verification rule.
- Many 'watch repair' assortments list a range of diameters (0.7-1.4mm) without confirming any single model uses exactly M1.2 — treat mixed assortments as reported, not confirmed.
- Many 'M1.2' eyewear listings mix up thread diameter with shaft/head diameter — ISO 11381 is the only authoritative dimensional standard for these threads.
- Otto Frei's watch-band clasp screws are described by shank diameter ('1.2 mm diameter') rather than an explicit 'M1.2' thread callout, so treat as reported, not confirmed metric thread spec.
- Framework lists both M1.2 x 3.0 silver and M1.6 x 3.0 black expansion-card screws; they look identical in the tray but are not interchangeable.
- Hearing aids and true wireless earbud charging cases (AirPods, Galaxy Buds) predominantly use ultrasonic welding, adhesive, or clip-based assembly rather than metric screws; no reliable source explicitly documents an M1.2/M1.4/M1.6 screw thread for these categories, so no confirmed entries could be included for hearing aids or earbud cases.
- Found in both dental handpieces and high-end gastrovideo scopes, requiring high precision slotted or headless drivers.
