Head styles & standards cross-reference
- Socket cap (cylindrical head)ISO 4762 / DIN 912M1.4 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 M1.4 — the trailing digits pick the exact length
- AccuSSC-M1.4-6-A2 (socket cap), SPP-M1.4-6-A2 (pan Phillips)Accu part codes are built as style-thread-length-material
- Bossard / WürthISO 4762 M1.4x6 A2-70European distributors order by standard + size + material grade, not a fixed SKU
- RS / Farnell / Digi-Key"M1.4 x 6mm" + head style + material in the parametric filterStock codes differ per region — search by the standard instead

Watch out for
- M1.4 is THE Samsung Galaxy internal screw across S, A, M and Note lines — but lengths run 2.3mm to 4mm+ and are not interchangeable between models.
- Sellers often list only thread diameter, so an M1.4x3 drone screw and an M1.4x2.3 phone screw look like the same product.
- Eyewear screws are named thread x shaft x length, a different convention from ISO metric naming — easy to order wrong.
- Whoop drone M1.4 comes in steel, PEEK and RENY versions: plastic ones are for cameras, not structural frame use.
- Eyeglass screws follow ISO 11381, a finer pitch than ordinary metric — a hardware-store M1.4 often will not thread in (https://standards.iteh.ai/catalog/standards/cen/6256292f-d7e8-4e31-bd55-1c1b2a8cc53b/en-iso-11381-2016)
- Dental implant screws (M1.4/M1.6) are proprietary per system — Bredent, NeoBiotech, Nobel and Straumann are not interchangeable even at the same nominal size.
- Phone guides describe screws by Torx bit size (T3/T4/T5) rather than thread; M1.4-M1.6 is inferred from shaft diameter, not stated by the maker.
- Whoop motor screws differ between M1.4x3mm and M1.6x4mm across BetaFPV/NewBeeDrone product generations — check the exact model.
- M1.4 is below common commodity stock; Mitutoyo sells these as branded service parts rather than generic hardware.
- Brass HO-scale locomotive coupler/truck screws are frequently metric and mismatched with US-made replacement stock, a recurring frustration noted on model railroad forums/blogs.
- Vintage/JIS camera lens mount screws are frequently confused: forum contributors note that ISO-metric fasteners this small are uncommon industrially, that thread pitch nomenclature is often mis-stated by hobbyists (e.g. mixing up 'M2.5/M2.6' with different pitches rather than diameters), and that finding correct *lengths* (not just diameters) is the harder problem — e.g. M1.6x15mm is described as 'impossible to find' commercially.
- Eyeglass vendors often quote 'head diameter x thread diameter x length' in mixed order (e.g. 5.2mm x 1.4mm x 2.5mm) — the 1.4mm figure is the thread/shaft diameter, not the head.
- Watch-brand OEM screw part numbers (e.g. Samsung) vary by exact model/size variant (42mm vs 46mm), so confirm the specific SKU matches the watch case size.
- iPhone-series OEM screws use both 'Main Screw' and 'Super Screw' names for M1.4 fasteners with different lengths per model/position — always match by dimensional code (L x D x T), not just model name.
- Micro-drone vendors sometimes label the same M1.4 screw family as 'motor screws' vs 'FC/ESC screws' with different lengths — length, not thread, differentiates use.
- Slice Engineering also lists 1.3mm and 2mm hex keys - those are driver sizes, not thread sizes.
- Fairphone does not publish an official screw spec; the M1.4 sizes come from caliper measurements on the community forum, so verify before buying in bulk.
- DJI drone teardown guides (Mini 2, Mini 4 Pro) list step-by-step screw removal but rarely publish an explicit metric thread designation in public sources; explicit M1.4 fitment evidence instead comes from the aftermarket FPV/whoop-frame community (RotorBuilds, IntoFPV), not from DJI documentation itself.
