Introduction of High strength bolts:
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.
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.

Features of high-strength bolts:
Material Composition:
High-strength bolts are typically made of alloy steel, such as ASTM A325 or ASTM A490 steel, which have higher tensile strengths compared to standard mild steel bolts.
The higher strength steel allows the bolts to withstand greater loads and stresses without compromising the connection.
Tensile Strength:
High-strength bolts have a minimum tensile strength of 120 ksi (825 MPa) for ASTM A325 bolts and 150 ksi (1035 MPa) for ASTM A490 bolts.
