Hybrid self-tapping screws
Categories: Self-tapping screws
Product Introduction
Hybrid self-tapping screws refer to self-tapping screws of various structural types, and the biggest feature is their high tensile force. It is generally used to connect thin metal plates to each other. When connecting, first make a threaded bottom hole for the connected piece, and then screw the screw into the threaded bottom hole of the connected piece. Since the threaded surface of the self-tapping screw has high hardness, the internal thread can be tapped in the threaded bottom hole of the connected piece to form a connection.
