The main functions of hexagonal flange bolts include providing a stable connection, transmitting force, and ensuring sealing. Its strong fastening force can firmly connect the flange and the connected components, ensuring the stability of the connection. In addition, the head of the hexagonal flange bolt is designed in a hexagonal shape, with a flat flange attached to the bottom. This structural design increases the contact area between the bolt and the fastened surface, which can disperse pressure and reduce damage to the substrate, especially suitable for soft materials or applications that require avoiding indentation.
