Self-tapping and self-drilling screws are highly efficient fasteners that integrate drilling, tapping and fastening. They can be directly installed on materials such as metal, wood and plastic without the need for pre-drilling. Its drilling tail design (such as cross-cut edges, triangular pyramids, etc.) can penetrate materials and simultaneously form mating threads, significantly enhancing construction efficiency. It is widely used in fields such as building steel structures, mechanical and electrical installation, and light steel roofs.
