J Bolts

J Bolts are headless bolt fasteners with bent profile in shape of letter J, used for anchoring pipes, round or square profile. J bolt provide partial support to structurals due to its open hook design. J anchor bolts are used with 2 hex nuts on either side of the anchoring roof or directly tapped into a hole. J bolts are often called bent hook bolts. Bent j bolts, j anchor bolts, j hook bolts are other alias of J bolts. J 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.
