High strength bolts transmit external forces by applying pretension and friction.
High strength bolts are generally used for permanent connections.
High-strength bolt connection has the advantages of simple construction, good mechanical performance, disassembly, fatigue resistance, and no loosening under dynamic load, so it is a promising connection method.
