Bent Arc Collar Stud

The Bent Arc Collar Stud, or bent collar 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 low carbon steel and stainless steel as standards, other special materials and grades are available. The bent collar stud is characterized by a base portion without threading which has a 90 degree bend has formed into it. This style weld stud transitions into an oversized mid-portion, or "collar", and external threads start above the collar. The collar diameter creates an offset 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.
