Self-Drilling Screws

Self-Drilling Screws

Self-drilling screws (often called Tek screws, after a common brand name) are specialized fasteners with a built-in drill bit tip at their point. This design allows them to drill their own pilot hole and tap threads as they are driven into the material, eliminating the need for pre-drilling.
