In terms of appearance, the combination screw has one more elastic pad or flat pad than the ordinary screw. This kind of combination screw is called two combination screws, and some have more elastic pad and flat pad. This kind of combination screw is three combination screws. The elastic pad and flat pad are installed before rubbing teeth, and the diameter of the washer after rubbing teeth is smaller than the tooth diameter. Therefore, the elastic pad and flat pad cannot be removed and combined with screws to form an assembly, which is the combination screw. Combination screws are mostly used for the connection between thin metal plates. 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 threaded surface of the combined screw, the internal thread can be tapped out in the threaded bottom hole of the connected part to form a connection. The purpose of cross recessed combination screw, hexagon head bolt combination screw and self tapping combination screw is the same as that of corresponding cross recessed screw, hexagon head bolt and self tapping screw. The main feature of these combination screws is that they are equipped with corresponding washers, which is very convenient to use.
