GR 8.8s HSFG Bolts are a type of fastener designed for high-strength applications, particularly in structural engineering and construction. These are manufactured from high-strength steel and are specifically designed to provide a high level of tensile strength and shear strength. They are installed with a predetermined tension or pre-load, which is achieved by tightening the bolts to a specified torque value. GR 8.8s HSFG Bolts are commonly used in the construction of buildings, bridges, and other structures where high-strength connections are essential. They are favored for applications requiring reliable and durable joints, especially in steel structures.
