Stainless steel machine screws in A2 (304) and A4 (316), from miniature M1 up to M16, for tapped holes, nuts and fitted hardware.
- Pan head (DIN 85, DIN 7985 and ISO 14583): a low, rounded head that sits proud of the surface.
- Cheese head (DIN 84): a taller cylindrical head with a slot, suited to counterbored holes.
- Countersunk (DIN 963, DIN 965 and ISO 14581): sits flush in a countersunk hole.
- Raised countersunk (DIN 964 and DIN 966): a countersunk head with a slight dome for a neater finish.
Drives are slotted, Pozi, Phillips or six lobe, depending on the style. Most styles run up to M8 or M10, and countersunk slotted screws go up to M16. A small number of imperial UNC, UNF and BSW machine screws are also listed. Pair with a matching nut for through-bolted joints, or drive into a tapped hole.
Sizes, grades and pack quantities vary by product type. Check the individual product listing for the exact specification and current availability.
