Structural Bolts are designed for the connection of structural members. These bolts are of high tensile strength and are used in conjunction with high strength nuts and hardened steel washers in structural steelwork. Sometimes they are abbreviated to HSFG (high strength friction grip) bolts when they are tightened to a specified minimum shank tension so that transverse loads are transferred across the joint by friction between the plates rather than by shear across the bolt shank. Information about structural bolts application, product and dimensions standards, tensioning methods for slip critical connections, joint preparation and precaution for slip critical connections is given in this article.
