M3 x 6 mm Countersunk Socket Screw, 304 Stainless Steel - CCSA2M3X6
Available
The Metric Countersunk Socket Head Screw, 304 Stainless Steel is available in 100 sizes (M3 to M16) and is a flat countersunk head screw driven by a hex key. The conical head sits flush in a countersunk hole for a flat finish.
A2 stainless (grade 304) gives sound general corrosion resistance for inside work, fresh water and ordinary outdoor exposure. It is not the grade normally chosen for coastal, pool or marine work, where A4 (316) is recommended. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.
You can choose from 100 variants, covering sizes M3 to M16 and lengths 6 mm to 100 mm. Variants are supplied in packs of 25 to 100, depending on size.
Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. Use stainless washers and nuts with stainless fasteners, so the whole joint is made of the same material.

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. Near the coast, around pools or in marine settings, use the A4 (316) version instead: Countersunk Socket Screw, A4 316 Stainless Steel, DIN 7991.
