Hillman Self Drilling Screws Hex Washer Head

The Hillman zinc plated, steel, self-drilling screw is used in wood, fiberglass, and metal, and possess a drill point enabling it to drill its own hole in thin gauge steel. The sharp threads create their own mating thread when drilled into the material. No pre-drilled pilot holes are necessary, making for easy installation. The external hex drive offers traction with a socket or wrench. The zinc finish offers moderate protection against rust and corrosion.
