ARC WELD STUDS: FULL BASE ARC FASTENERS

The Full Base Arc Stud is a 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, stainless steel and Aluminum as standards, other special materials and grades are available. Similar to the Standard Thread weld stud, the full base style is characterized by external threads for a majority of the weld stud length, and a non-threaded base equal in diameter to the full diameter of the threads. Studwelding of the weld stud burns off a portion of the base so that the pre-weld, post-weld length dimensions should be considered. All orders for arc weld studs from Midwest Fasteners include ceramic studwelding ferrules properly sized for the weld stud ordered.
