Weld screws, also known as weld studs or projection weld fasteners, are advanced threaded fasteners designed to create permanent, high-strength connections using resistance or arc welding methods. These screws feature specially engineered projections, rings, or cone-shaped tips that provide consistent weld quality and immediate structural integrity. By eliminating the need for pre-drilled holes, tapping, or backside access, weld screws enable fast, reliable fastening in thin sheets, sealed panels, and confined assemblies.
Precision-engineered for demanding industrial environments, weld screws form a metallurgical bond with the base metal, offering exceptional resistance to vibration, shear stress, and pull-out forces. Available in both metric and inch configurations, they come in externally threaded stud styles, internally threaded tap pads, and pin-type designs for flexible integration into different manufacturing systems. Stainless steel weld screws provide corrosion resistance for outdoor or marine applications, while copper-plated versions ensure excellent conductivity for reliable resistance welding. Their rapid installation often within milliseconds significantly reduces assembly times and eliminates the need for extra hardware such as rivnuts, PEM nuts, or weld nuts.
