What is the fastening principle of Tapping screws?

The fastening principle of Tapping screws is mainly based on its unique thread structure and sharp end design.
The thread of Tapping screws is usually sharp and has a certain cutting ability. When the screw is screwed into the material, the sharp thread will cut the material to form a matching thread. At the same time, the pitch of the screw is relatively large, which can generate a large axial thrust during rotation, gradually pushing the screw into the material.
During the fastening process, as the screw continues to go deeper, friction and bite force are generated between the thread and the material, thereby achieving a fastened connection. This fastening method enables Tapping screws to form threads directly on the material and provide a reliable connection without the need for pre-tapping.
