Self Drilling Screws

Self-drilling screws, often known as Tek screws, are designed to drill their own pilot hole and form a mating thread in a single operation. They feature a hardened drill-point tip that cuts through metal, followed by the screw threads that secure the fixture. This one-step process significantly reduces installation time by eliminating the need for pre-drilling. They are essential for fixing to steel sections, purlins, and for general metal fabrication, available with hex heads for high-torque driving or pan heads for a lower-profile finish.
