Flange Stud Bolts

Flange Stud Bolts

Stud bolts implied for bolting pipeline flanges, are called flange stud bolts. These flange studs have continuous threaded body and chamfered ends. Engagement length is considered from first threaded to last thread, excluding the chamfered ends. One of the dimension standards for flange stud bolts is ANSI/ASME B16.5. Length calculations are done according to the size and pressure-temperature ratings of the flange. Flange 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.
