HSFG Washer is typically used in conjunction with high-strength bolts in structural steelwork and HSFG stands for High Strength Friction Grip. The offered system involves the use of bolts that are tightened to a specific high tension, creating friction between the connected structural elements. These components are commonly used in construction and engineering applications where maintaining the integrity of the joint is crucial. They are usually hardened and provide a smooth, flat surface under the bolt head or nut to distribute the load evenly. HSFG Washer is widely used in structural steel connections, such as in bridges and buildings, where the reliability and stability of the connections are paramount.
