The Shoulder Arc Stud is a partially threaded weld stud for application with arc stud welding equipment. This type of stud welded fastener is usually flux-loaded on the weld end for studwelding applications. Available in Mild (Low Carbon) Steel and stainless steel, other special materials and grades are available. The shoulder stud is characterized by a base portion without threading and external threads starting above the unthreaded portion, or base. The difference in diameter of the base versus the threaded portion creates a "shoulder", which is often used for part mounting and stand-offs in design. Studwelding of the weld stud burns off a portion of the base so that the pre-weld, post-weld length dimension should be considered. All orders for arc weld studs from Davis Stud Welding include ceramic studwelding ferrules properly sized for the weld stud ordered.
