ASTM A325 high-strength structural bolts are designed for use in structural connections, therefore they have shorter thread lengths than standard hex bolts. They feature a heavy hex head, full body diameter. Unlike other grades, ASTM A325s are specific not only in chemical and mechanical requirements, but also in allowable configuration.
