Product：

Tapping screws, or quick thread screws, are quick fasteners made of steel with galvanized passivation. Tapping screws are used to connect thin metal plates (steel plates, saw plates, etc.). When connecting, the threaded bottom hole of the connecting piece is made first, and then the tapping screw is screwed into the threaded bottom hole of the connecting piece.

Tapping screws combine taps with bolts. The front is the tap, the back is the thread. In general soft materials, drill a hole can be directly screwed into. Tap the thread from the tap, followed by the bolt thread. If the screw diameter is small, the material is also very soft. You don't even have to punch a hole first, like screw it into a piece of wood.
