Double end stud bolts are threaded rods with equal thread length at both ends. Tap end studs are also sometimes referred as double end stud bolts. Double end stud bolts have plain shank equal to that of the nominal diameter. Double end studs are used for high strength bolting. Further one type of double end stud bolts have reduced shank diameter as designed for special bolting. DIN 2510 is specification for double end stud bolts with reduced shank. Double end stud 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.
