Slotted self-tapping screws (or “sheet metal screws”) are threaded fasteners with self-tapping capabilities. They feature coarse threads and a slotted head, allowing them to be quickly driven into thin metal, plastic, or wood using a flathead screwdriver without the need for pre-tapping. These screws are widely used in industries such as electronics, furniture assembly, and automotive components, offering the advantages of ease of installation, cost-effectiveness, and high resistance to loosening.
