Portland Bolt & Manufacturing Company

Structural Bolts

Structural Bolts

Heavy hex structural bolts are designed for steel-to-steel structural connections. Consequently, they are typically very short. Unless otherwise specified, F3125 structural bolts will have a Unified National Coarse thread pitch. The F3125 Grades A325 and A490 specifications are not intended for general applications, including anchor bolts.

Manufacturing

Portland Bolt 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.
