Friction grip bolts are commonly used in structural steelwork. The bolts are tightened to a shank tension so that the transverse load across the joint is resisted by the friction between the plated rather than the bolt shank's shear strength. Hot-dip galvanizing, like other coatings, isolates the steel from the environment providing basic, barrier protection to ensure longevity.
