ASTM Bolt Tap End Stud
Stud bolts known as studs are categorized into 3 basic types: Tap End Stud Bolts, Fully Threaded Stud Bolts, and Double End Stud Bolts. Each of these has different engineering applications. Tap end studs have threads at extreme ends of the stud having unequal thread length, but double end stud bolts are differed in that they have equal thread length at both ends. Fully threaded studs are threaded fully across the body for full engagement of the matings nuts or similar parts.
