ARC WELD STUDS: TAPPED ARC FASTENERS - REDUCED BASE

The Tapped Reduced Base Arc Stud is a plain shank 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, stainless steel and Aluminum, other special materials and grades are available. The tapped style is characterized by a stud body with no external threading and internal threading provided inside the weld stud body. The reduced base style provides a diameter that allows studwelding fillet formation no larger in diameter than the full diameter of the stud body. 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.
