About Countersunk Screws: A countersunk screw is a type of fastening that sits flush with the surface of the material it occupies. These screws typically are used so that you can cover them easily with either a screw cap or piece of wood. Other applications include the need for a fastening not to protrude so other objects can rest upon it stably, or to fasten it further to another object.
