Heavy hex structural bolts are designed for steel-to-steel structural connections. Consequently, they are typically very short. The A325 and A490 specifications are not intended for general applications, including anchor bolts. In these applications, substitutions of A449 for A325 and A354 grade BD for A490 should be considered.


Shree Ram Fastners manufactures A325 and A490 heavy hex structural bolts from 1/2″ diameter through 1-1/2″ diameter, typically in lengths longer than those which are normally available in the marketplace.
