Self Drilling Screws
A self-drilling screw is a hardened fastener featuring an integral drill point at its tip, designed to drill, tap, and fasten in a single operation—eliminating the need for a pre-drilled pilot hole. This "three-in-one" capability makes it the most efficient solution for joining metal-to-metal, metal-to-wood, and metal-to-composite applications in high-volume construction and industrial fabrication.
