Countersunk Socket Screw, 304 Stainless Steel - CCSA2M4X45

The Countersunk Socket Screw M4 x 45mm, 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.

Both A2 (304) and A4 (316) stainless steel variants are listed here, and the grade is shown on each variant. Use A2 for indoor, fresh water and general outdoor work, and A4 where chlorides are present, such as coastal, pool and marine settings. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

This listing has 2 variants. Each variant is supplied in packs of 100.

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.

Key specifications

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.
