Large hexagonal head structural bolts A325 Intended for structural bolting uses, is an international standard for heavy hex structural bolts set by ASTM International (American Society for Testing and Materials). A325 bolts are commonly used in construction and structural engineering projects such as bridges, buildings and other load-bearing structures. These bolts have a heavy hexagonal head that provides a larger surface area for a wrench or socket to apply torque.
