Earnest's line of structural fasteners are manufactured to the requirements of ASTM for use in the construction and remodeling of buildings, warehousing wind turbine towers and general construction. Heavy hex structural bolts are designed to ensure the clamp loads developed in the assembly are distributed over a larger area than a standard hex heads. They also provide a larger wrenching area to resist rounding off of the head. Structural bolts are available in “cans” to protect them from weather and harsh job site conditions and can be shipped right to the job site.

Heavy Hex Structural Bolt – A325
