Introduction of High strength bolts:
High strength bolts are made of high strength materials. The screw, nut and washer of the high-strength bolt are made of high-strength steel.
High-strength bolts are a type of fastener commonly used in the construction of steel structures, such as bridges, buildings, and industrial facilities. These bolts are designed to provide a strong, reliable connection between structural steel members, ensuring the overall stability and integrity of the structure.
Applications of high-strength bolts:
Structural Steel Framing:
High-strength bolts are extensively used to connect steel beams, columns, and other structural members in the construction of steel-framed buildings, bridges, and industrial facilities.
They provide the necessary strength and rigidity to the structural connections, ensuring the overall stability and load-bearing capacity of the building or structure.
Bridge Construction:
High-strength bolts are critical components in the construction and repair of bridges, where they are used to connect the various steel elements of the bridge superstructure and substructure.

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.
