The combination screw generally has two combination screws and three combination screws, that is, one screw is equipped with a spring washer and a flat washer. A screw that is then screwed together.

The material is generally divided into carbon steel and stainless steel, which are mostly used for the connection between thin metal plates and play the role of connection. When connecting, first make a threaded bottom hole for the connected part, and then screw the combined screw into the threaded bottom hole of the connected part. Due to the high hardness of the thread surface of the combination screw, the internal thread can be tapped out in the bottom hole of the thread of the connected part to form the connection.
