Arc Weld 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. Due to the slightly larger base diameter, the Pitch Diameter Stud will have a higher shear value than the same size Full Thread Stud. However, since a Pitch Diameter Stud is not fully threaded, it is best suited when there is a mating part that covers the unthreaded portion of the weld stud so make it is appropriate for your specific application.
We stock lengths up to 3″, beyond 3″ is considered a custom order. Please contact us for your specific needs.
