Head styles & standards cross-reference
- Socket cap (cylindrical head)ISO 4762 / DIN 912M1.6 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.
- McMaster-Carr91290A### (alloy socket cap), 92095A### (flat head), 92005A### (pan Phillips)Catalog families for metric M1.6 — the trailing digits pick the exact length
- AccuSSC-M1.6-6-A2 (socket cap), SPP-M1.6-6-A2 (pan Phillips)Accu part codes are built as style-thread-length-material
- Bossard / WürthISO 4762 M1.6x6 A2-70European distributors order by standard + size + material grade, not a fixed SKU
- RS / Farnell / Digi-Key"M1.6 x 6mm" + head style + material in the parametric filterStock codes differ per region — search by the standard instead
Watch out for
- M1.6 is the most common laptop-internal micro screw after M2 — Dell XPS keyboards specifically call out M1.6 x 1.5mm, and generic M2 substitutes strip the bracket.
- BETAFPV sells the same motor mount in M1.4x3 and M1.6x4 — match the motor's tapped hole or you cross-thread it.
- Heavier metal sunglass hinges use M1.6 while acetate frames use M1.4 or M1.2; you cannot tell without calipers.
- M1.4 and M1.6 differ by 0.2mm — an assortment kit for test-fitting beats guessing from teardown photos.
- Consoles like PS5, Xbox and Switch mostly use Torx, Torx Security or tri-point Y00 heads rather than plain metric hex — the driver matters as much as the thread (https://www.ifixit.com/Wiki/Nintendo_Switch_Screwdriver)
- Steam Deck backplate screws are M1.6, not M2 as commonly assumed — check the iFixit Screw ID guide before ordering.
- Apple's own part naming mixes thread (M1.6) with head diameter (H3.0/H3.2) — read the full part description carefully to avoid conflating head size with thread size.
- 'M1.6 Phillips screw' complaints on forums (e.g. MacBook Air trackpad) describe diameter by eye/caliper rather than an official spec — these are useful corroboration but not primary confirmation.
- M1.6 is far more common as a generic miniature machine-screw/set-screw size (electronics enclosures, precision instruments) than as a device-specific fitment; require a device-specific product page, not just a generic hardware size chart, before treating a hit as an 'application'.
- Steam Deck (LCD) mixes M1.6 and M2 screws with near-identical heads at 3, 3.5, 4 and 4.5 mm — swapping them cross-threads the plastic. Match by the iFixit Screw ID guide.
- Headphone hinge screw sizes are usually quoted from screwdriver bit size, not an actual thread spec - measure before buying.
