Overall Length
threads on a Full Thread Stud run the full length of the fastener
(hence full thread). This simplifies many mating part concerns
and is a favorite of engineering. Also, a Pitch Diameter Stud
requires that the mating part(s) cover the unthreaded portion of
the fastener. Also, a Pitch Diameter Stud is marginally stronger in
shear than a Full Thread Stud due to the slightly larger diameter
in the shear area.
