DOUBLE END STUDS

DOUBLE END STUDS

Double end studs have threads on both ends of the same thread fit class. This is usually class 2A, or if looser tolerances are allowed, commercial nut fit. The body, the area between the threads, may be either equal to the nominal major diameter of the threads or equal to the pitch diameter.
