Titanium hexagon socket countersunk head screw

Countersunk screww,also known as countersunk screw.also known as flat screw,is a construction part.The head is a 90 degree cone,similar to the common wood screw,the head has a tool tightening slot,a font,a cross,an inner hexagon,a club shape,a pentagon and so on.

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. Countersunk screws can be sunk under the surface to make the surface flat, and harder objects need 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.
