Steel City Bolt has been PennDot approved for many years on such products as F1554 gr 55 anchor bolts and anchor rods and headed items.We are pleased to announce we are now PennDot approved on A325 Heavy Hex Bolts. (A325 bolts are now a grade of bolt covered under ASTM F3125.)

Call us 800-522-2658 or email at for your A325 bolt needs and the requirements under ASTM F3125. The ASTM A3125 specification covers high strength heavy hex structural bolts from 1/2″ – 1-1/2″ in diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts. Refer to the A325 Heavy Hex Structural Bolt page of our site for thread lengths and other related dimensions.
