Details

Alias: Bent J Bolts, J Anchor Bolts, J Hook Bolts;

J Bolts are headless bolt fasteners with bent profiles in the shape of the letter J, used for anchoring pipes, and round, or square profiles. J bolt provides 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, and j hook bolts are other aliases for J bolts. J bolt 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 specifications.

Browse the page for information on the J bolt manufacturing process, forming method, available sizes, sub-types, thread types, metric and imperial dimension standards, weight charts, torque values, material categories, grades, and ASTM specifications.

Manufactured in mild Steel Zinc Plate and Stainless Steel as standard.

Non-standard sizes, materials, and finishes are available to order as specials, including small-volume manufacture, modifications, and bespoke parts made to drawings. Minimum order quantities apply.
