Tension Control Bolts

Tension Control Bolts

 

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.
