The countersunk screw 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. Slot screw head has a single horizontal indentation (the slot) in the fastener head and is driven by a flat-bladed screwdriver. Brass finish provides protection through a reaction of the surface to oxygen, creating a protective chromium oxide film.
