Everbilt 45-Piece Zinc-Plated Self-Drilling Sheet Metal Screw Kit

These sheet metal screws or self-drilling screws, are highly versatile and are used to attach metal, wood, fiberglass and plastic. The sharp threads draw material together and ensure a secure hold. Made from hardened steel, the threads create their own mating thread in pre-drilled holes. Sheet metal screws are fully threaded with a sharp point.
