Headed anchor bolts are different from bent anchor bolts or anchor rods, because the non-threaded end has a forged hex, heavy hex or square head. The headed end is embedded into concrete foundations to secure structural steel columns, light poles, bridge rail, and substation structures. Available specifications include, but are not limited to, ASTM F1554, A449, and A307.
Shree Ram Fastners manufactures headed anchors from 1/2″ through 2-1/2″ diameter in many different ASTM specifications. They are provided either plain finish or hot-dip galvanized.
