Product Description

   

Product Description

The main function of hexagonal flange with gasket bolts is to provide reliable connection and fixing function. The bolt is composed of a hexagonal head, a flange and a screw. By combining with the nut, it can securely connect two parts with through holes. The design features include a flange and a toothed part, the flange increases the contact area, and the toothed part plays a non-slip role to ensure that the connection state can be maintained under various working conditions .

The specific application scenarios of hexagon flange with cushion bolts are very wide. In the aviation industry, these bolts are used to connect aircraft structural components and are able to withstand extreme temperature changes and aerodynamic loads to ensure flight safety 4. In heavy vehicle manufacturing, such as the construction of trucks and ships, these bolts are used to secure body structures and key components and are able to withstand corrosion and vibration in road and Marine environments 4. In addition, hexagonal flange with gasket bolts are also used in high-rise buildings, pipeline connection, electronic equipment, mechanical parts and other fields to ensure structural stability and safety .

The design features of hexagonal flange with cushion bolt include the hexagonal head, flange and tooth part. The flange increases the contact area between the bolt and the connected piece, improves the stability of the connection and the distributed stress, and prevents the damage caused by excessive force at a single point. The toothed part plays an anti-slip role, especially under vibration or alternating load conditions, to ensure that the bolt will not loosen.
