ARC WELD STUDS: SHOULDER ARC FASTENERS - NO THREAD

The Shoulder No Thread Arc Stud, or shoulder pin stud, is a two part non-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 low carbon steel and stainless steel, other special materials and grades are available. The no thread shoulder stud is characterized by a plain base portion and a smaller diameter unthreaded section starting above the base. The difference in diameter of the base versus the threaded portion creates a "shoulder" 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 Midwest Fasteners include ceramic studwelding ferrules properly sized for the weld stud ordered.
