Structural Bolts

A325 and A490 bolts are large hex structural bolts that are designed to handle the loads of steel-to-steel connections. The head of the heavy hex structural bolt is defined to have the same size as the heavy hex nut of the same nominal diameter, allowing the bolt head and nut to be accessed with the same size wrench or socket. Because structural bolts are intended for steel-to-steel connections, they have a shorter shank/thread length than normal hex bolts or hex cap screws.
