Metric

Countersunk Socket Head Screws are characterised by their cylindrical, hexagonal socket drive and a head that is designed to sit flush with the surface of the material. The head of the screw is conically shaped, allowing it to be recessed into the material, which reduces the risk of snagging and provides a streamlined appearance. Generally manufactured to property class 10.9. Metric Countersunk Socket Head Screws are designed according to the metric measurement system, with thread dimensions specified in millimetres.
