Heavy Hex Bolts

Heavy Hex Bolts are similar to hex head bolts but with large width across flats and thickness. Heavy hex bolts are mostly produce in high tensile, material grades and specifications, for use in high strength structural applications. Heavy hex head 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.Browse the page for information on heavy hex 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.
