Weld Nut

Name: Weld Nut
Brand: YONGYI

Product Introduction Weld nuts are specialized threaded fasteners designed for permanent fixation on metal workpieces, primarily crafted from high-strength carbon steel or stainless steel. Featuring a unique structural design with welding lugs or projection points, these nuts enable stable and firm welding to the surface of metal plates through processes like spot welding or projection welding, eliminating the need for pre-drilled threaded holes. The product undergoes precise thread rolling and heat treatment, ensuring excellent thread accuracy and tensile strength, while its surface can be treated with galvanizing, dacromet coating or electrophoresis for enhanced corrosion resistance and wear resistance. Compatible with standard bolts, weld nuts deliver reliable fastening performance and are widely recognized for their high installation efficiency and structural stability in automotive manufacturing. Product Application Mainly applied in the assembly of automotive body structures, including the fixation of door hinges, seat brackets, chassis reinforcement plates and dashboard mounting bases. They are also extensively used in the manufacturing of commercial vehicle compartments, engineering machinery cabins and agricultural equipment frames, serving as an essential fastener for achieving permanent and stable connections in thin metal plate assembly scenarios.
