Stud bolts and nuts for flanges (definition, sizes, materials) in metric and imperial sizes ASME B16.5

Stud Bolt for Flanges (ASME B16.5)

What is a stud bolt? Stud bolts for flanges consist of a fully threaded steel rod and two heavy hexagonal steel nuts. Stud bolts are inserted in the flange holes and tightened to seal a flanged joint. The number, the length, the diameter of the stud bolts required for a flanged connection depend on the… read more »
