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.
