Description

Countersunk Screw – a machine screw with a flat, cone-shaped head that seats flush with the surface it fixes, leaving no proud edge.

Metric M6 thread with a 20 mm shank length. Used where a flush finish is needed, such as securing gear change components, door lock parts, seat supports and bonnet release mechanisms, the tapered head pulls down into a matching countersink so the fixing sits level with the panel.
