Structural Bolts

A specialized, heavy hex bolt designed to withstand the loads of steel-to-steel connections, structural bolts are intended for use in constructing buildings, bridges and other large structures. Tension control bolts, or "twist-off" bolts, are another species of specialized structural bolt that aids in determining correct torque. When installed with the required wrench, the splined extension of the bolt disconnects when the bolt tension reaches a pre-determined value.
