Metal screws are usually cylindrical and are bolted to a mating thread (nut). Both wood and metal screws are mostly made out of metal themselves.
Stainless steel screws are made of stainless steel, nickel or copper alloys, aluminum, titanium, carbon, or even plastics. Simple steel screws require a coating if they are not installed in corrosive conditions.
DIN-standards / ISO standardization:
Standards specify design features and textures, so a certain screw is always the same screw. Among other things, the shape of the screw head, diameter, thread type and length are defined.
Common screw head styles: Flat head, round head, fillister head, countersunk head, hex head or cylinder head. In combination with the head shape, a wide variety of screw head drives are available: slotted, cross, torx, pozidriv or TX-multitooth are a few, with many others available.
