These sheet metal screws， or tapping screws， are highly versatile and are used to attached 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. Self drilling sheet metal screws are fully threaded and possess a drill point enabling it to pilot in its own hole in light gauge steel. No pre drilled holes necessary.
