Spring washers are specialized mechanical components designed to provide a resilient and flexible interface between two surfaces, typically in bolted or threaded assemblies. Their primary function is to absorb shock, maintain tension, and prevent loosening of fasteners due to vibrations or dynamic loads. These washers are characterized by their unique shape, which often resembles a conical or helical spring, allowing them to exert a consistent force even as the assembly undergoes movement or thermal expansion. By distributing the load evenly across the surface, spring washers enhance the overall stability and reliability of mechanical connections, making them essential in various applications across industries such as automotive, aerospace, and machinery.
