Flange bolts consist of a hexagonal head with a flange and a screw. Flange nuts consist of two parts: the nut body and the flange. The body of the nut has a threaded hole that matches the bolt, while the flange increases the contact area between it and the connecting parts, improving the stability and load-bearing capacity of the connection.
Flange bolts and nuts are widely used in construction, bridges, vehicles, ships and other types of projects for connecting and fixing various components. When selecting and using them, their specifications, materials and performance levels should be determined according to the actual working conditions and use requirements, and ensure that the selected products comply with the relevant standards and norms.
During the installation process, it should be ensured that the threads of bolts and nuts are well matched to avoid the phenomenon of jamming or slipping threads, and should be tightened according to the specified torque to ensure the reliability of the connection. In addition, check the tightening status of flange bolts and nuts regularly to find and deal with loosening, corrosion and other problems in time.
