Hexagonal flange bolts are also called hexagonal flange bolts, which means that the head of the bolt is a hexagonal head (some of the heads are flat and some are concave) and flanges (the gasket under the hexagon and the hexagon are fixed as a whole ) And a screw (cylinder with external thread) composed of two parts of a one-piece bolt, in short, it is a bolt composed of a hexagonal head, a flange and a screw.

The bolts are divided into two types according to the connection force: ordinary and reamed holes. The flange bolts used for reaming holes must match the size of the holes and are used when they are subjected to lateral forces. In addition, in order to meet the locking function of the bolt after installation, there are holes for the bolts to be provided in the rod. The function of these holes is to prevent the bolts from loosening and falling off when they are subjected to vibration.
