These bolts differ from anchor rods or bent anchor bolts in the sense that their non-threaded end come with a square head, forged hex or heavy hex. In order to protect structural steel columns, bridge rail, light poles and substation structures, the headed end of the anchor bolts is generally embedded into concrete foundations. Available specifications include ASTM F1554, A449 & A307.

Manufacturing

Baseline Bolt manufactures headed anchor bolts of diameter 1/2″ through 2-1/2″ in a range of different ASTM specifications. Moreover, they are provided with either plain or hot-dip galvanized finish.

Stock F1554 Grade 36 Headed Anchor Bolts

The following sizes and finishes are stocked at baseline Bolt under the given part number.

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.

Hex & Heavy Hex Blank Stock

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.
