ASTM F1554
This specification covers straight and bent, headed and headless, carbon, carbon boron, alloy, or high-strength low alloy steel anchor bolts (also known as anchor rods). The anchor bolts are furnished in three strength grades The anchor bolts are intended for anchoring structural supports to concrete foundations. Such structural supports include building columns, column supports for highway signs,street lighting and traffic signals, steel bearing plates, and similar applications.
* Optional welding & Counter-Punching/ Tighten Torque.
