Foundation bolts are long threaded bolts, straight or bent in different styles, used for anchoring steel profiles and plates to concrete. They are coupled with hex nuts and plate washers to secure the joint. Foundation bolts are often used in bent profiles such as J and L. Also known as anchor bolts or bent bolts, foundation bolts come in many types, sizes and external coatings, depending upon its application. Their dimensions are defined in both metric and imperial 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 standards. ASTM A307, A325, A354, F1554 are most commonly supplied specifications for foundation bolts.
