The Metric Countersunk Socket Head Screw, 316 Stainless Steel is a flat countersunk head screw driven by a hex key. The conical head sits flush in a countersunk hole for a flat finish.
The range runs to 98 variants, covering sizes M3 to M16 and lengths 6 mm to 100 mm. Pack quantities depend on size: packs of 25 to 100.
A4 (316) stainless steel contains molybdenum (about 2 to 3 per cent), which improves its resistance to chlorides. It is the grade normally chosen for coastal, pool, marine and food-processing settings, and it costs more than A2 (304). Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.
Stainless threads can gall (seize) when tightened under load or at speed. A smear of anti-seize on the thread and a steady tightening speed reduce the risk.

Selecting the right option
The material needs a countersink cut to suit the head angle and depth. Use the correct hex key, and use anti-seize on the thread, because stainless threads can gall. Where chlorides are not a concern, the A2 (304) version costs less: Metric Countersunk Socket Head Screw - 304 Stainless Steel.
