The Hex Washer Head Self-Drilling Screw is a versatile fastener that combines drilling and fastening in one step. Its hexagonal head provides a secure grip for easy installation using a screw gun, eliminating the need for pre-drilling holes. These screws are commonly used for attaching metal to wood or sheet metal to sheet metal. Their self-drilling feature creates their own hole and forms a mating thread during installation. With durability and convenience, they’ve become essential in construction, woodworking, and metalworking projects.
