Hillman #12 x 1 1/2″ Washer Head Self Drilling Screw 100pk

Self-drilling screws are manufactured for use in wood, fiberglass and metal. They possess a drill point which enables the screw to drill its own hole in thin gauge steel. The sharp threads create their own mating thread when drilled into the material, and provide a stronger grip to your surface.
