Self-tapping screws or quick-thread screws are quick-fit fasteners made of steel and passivated by galvanizing the surface. Self-tapping screws are mostly used for the connection between thin metal plates (steel plates, saw plates, etc.). When connecting, first open the threaded bottom hole for the connected piece, and then screw the Self-tapping screws into the threaded bottom hole of the connected piece.
