There are differences in the mechanical properties and calculation methods between ordinary bolts and high-strength bolts. The force on high-strength bolts is first exerted by applying a pre tension force P inside them, and then generating frictional resistance on the contact surface of the connected parts to withstand external loads, while ordinary bolts directly bear external loads.

High strength bolt connection has the advantages of simple construction, good stress performance, detachable replacement, fatigue resistance, and non loosening under dynamic loads, making it a promising connection method.

Our company specializes in: grid accessories, grid bolts, grid engineering, high-strength bolts, steel structural bolts, and high-strength nuts.
