M10 x 120 mm Countersunk Socket Screw, 316 Stainless Steel - CCSA4M10X120
Available
The Countersunk Socket Screw, A4 316 Stainless Steel, DIN 7991 is a flat countersunk head screw driven by a hex key. The conical head sits flush in a countersunk hole for a flat finish.
You can choose from 4 variants, covering sizes M8 to M10 and lengths 120 mm to 150 mm. Every size comes in packs of 25.
Supplied in 316 (A4) stainless steel. The molybdenum in A4 gives better resistance to chlorides than A2 (304), so it is the usual choice near the coast, around pools and in marine and food-processing environments. 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. 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. Where chlorides are not a concern, the A2 (304) version costs less: Metric Countersunk Socket Head Screw - 304 Stainless Steel.
