These bolts are different from the anchor rods or the bent anchor bolts as their non-threaded end comes with a forged hex, square head, or heavy hex. To safeguard the structural steel columns, light poles, bridge rail, and substation structures, headed end of anchor bolts is usually embedded well into concrete foundations. And, available specifications include A449, ASTM F1554 and A307.

baseline Bolt stocks these F1554 grade 36 hex head anchor bolts that are ready for immediate shipment. These hex bolts have a forged hex head and are not a rod with a tack welded nut. We stock a wider range of F1554 grade 36 headed anchor bolts in a hot-dip galvanized finish than in a plain finish.
Galvanized anchor bolts can usually be substituted for plain finish anchor bolts, especially when a quick delivery is required. If substituting a galvanized anchor bolt is not acceptable, baseline Bolt can always manufacture F1554 grade 36 headed anchor bolts in a plain finish. All stock F1554 headed anchor bolts have a 6” thread length.

baseline Bolt stocks both F1554 Grade 36 and F1554 Grade 55 hex and heavy hex head blanks (round bar with a forged head) in lengths of 36”. These blanks can be cut to length, threaded, and galvanized (when required) very quickly. Blanks are perfect for manufacture relatively small runs of custom sized F1554 headed anchor bolts with very short lead times.
