HIGH STRENGTH FRICTION GRIP BOLTS
abbreviated to HSFG bolts. Bolts which are of high tensile strength used in conjunction with high strength nuts and hardened
steel washers in structural steelwork. The bolts 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.
