Self-Drilling Screws, also known as Tek screws, eliminate the need for a pre-drilled hole. The length of the drill point determines the material thickness which the screw can reliably penetrate. When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined. These sheet metal 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.
