A2 (304) stainless steel is the common general-purpose austenitic grade. It resists corrosion well indoors, in fresh water and in most general outdoor conditions, but it is not recommended where chlorides are present, such as coastal, pool and marine settings. Choose A4 (316) there. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.
Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. In wet conditions, keep stainless steel apart from aluminium and galvanised steel with a washer or sleeve, to reduce the risk of galvanic corrosion.

Selecting the right option
The material needs a countersink cut to suit the head. Use a correctly sized Phillips driver and avoid power drivers at speed. A drop of anti-seize on the thread helps prevent galling. For coastal or chloride-exposed use, choose the A4 (316) version: Metric Phillips Head Countersunk (Machine) Screw - 316 Stainless Steel.
