This countersunk bolt is the best-fitting head shape for countersunk holes among domestic socket manufacturers. As it is a countersunk head with a hexagon socket, it can be tightened more strongly than a machine screw. It is used in situations where the level of tightness provided by a machine screw is insufficient, and where a protruding head would cause problems.
