About Stud Bolts

Stud Bolts

Stud Bolts – The stud bolt is a threaded rod with two heavy hexagon nuts. In the Oil and Gas Industry the fully threaded stud is the most common bolt used for flanged connections. The quantity of bolts for a flanged connection will be determined by the flange type and pressure class. Other type of stud bolts include double ends (threaded both ends only), tap ends (for threaded holes) and step downs (ends have different diameters). Stud bolts are available in all thread pitches (UNC/UNRC – UNF/UNRF – 8UN) diameters and metric sizes.
