Collar Studs are used to provide a spacer between the parent metal and the part secured on threaded extension.

Arc stud welding is a process by which a metal fastener is welded to a parent metal through a fusion weld. Using a “ferrule” to capture and retain the weld’s heat, the molten metal created by the process cools and the weld site and produces a weld that is stronger than the stud itself. Drawn arc stud welding can weld dissimilar metals such as mild and stainless steel, as well as aluminum.

Our Collar studs are composed of low-carbon steel or stainless steel. All purchases of Collar studs come with the necessary ferrules required for welding, so you do not have to worry about making sure you have the necessary parts!
