Anchor Bolts are long bolt fasteners used for fastening steel plates, profiles and similar steel structures to concrete. Anchor bolts are also known as Concrete anchor bolts or just concrete bolts. Anchor bolts have long threaded end for engagement with nuts and a unique anchor mechanism, respective to its use. Anchor bolt comes in many types, sizes and external coatings, depeding upon its application. Anchor bolts are coupled with nuts and washers. Anchor bolt dimensions are defined in both metric and imperials sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread profile. These are produced across all material categories and astm specifications. ASTM A307, A325, A354, F1554 are most commonly supplied specification for anchor bolts.
