When to use high strength bolts？
2025-04-11The mechanical properties and calculation methods of ordinary bolts and high-strength bolts are different. The force of the high-strength bolt is first to bear the external load by applying a pre-tension P inside it, and then generating friction resistance on the contact surface of the connected part, while the ordinary bolt is directly subjected to the external load. High-strength bolt connection has the advantages of simple construction, good mechanical performance, removable, fatigue resistance, and no loosening under dynamic load. It is a promising connection method.
