After forming, they are rubbed and cylindrical. The head is flat, such as an inclined surface surrounding the side of the screw, so that the screw can lock the screw cap or other objects tightly.

The protruding top also prevents the screw from being drilled too deeply through the material, and increases the pressure of the screw on the material.
