Threaded Studs

Pitch Diameter and Full Thread Studs are the two most common types of standard drawn arc weld studs. The primary advantage of a Pitch Diameter Stud versus a Full Thread Stud is in shear value. The Pitch Diameter Stud will have a higher shear value than the same size Full Thread Stud. This is due to the slightly larger base diameter of a Pitch Diameter Stud. However, since a Pitch Diameter Stud is not fully threaded, it may not be appropriate for your specific application. A Pitch Diameter Stud is best suited when there is a mating part that covers the unthreaded portion of the weld stud.
