About product

Screws are used to connect two pieces of connectors, generally the head of the screw will be protruded in the upper surface of the connected object, so that the surface is not smooth. Hexagonal Countersunk Screw can be sunk under the surface to make the surface flat, and the harder object needs to drill countersunk holes in the corresponding position of the countersunk head. In short, the countersunk head is the head of the screw that can keep the surface flat after installation.
