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. Teks self-tapping screws provide secure fastening with strong holding power without the need to pre-drill. Engineered drill-point and flute remove material efficiently and properly size the hole for threads.
