Manufactured from high-performance spring steel or stainless steel through specialized heat treatment, Aozhan spring washers deliver exceptional elasticity per GB/T 93 specifications. The distinctive split-ring design generates continuous tension to compensate for vibration-induced preload loss and thermal expansion/contraction effects. Featuring zinc-plated or Dacromet-coated surfaces for corrosion resistance, these industry-standard anti-loosening devices are essential for vibration-prone applications including industrial machinery, automotive chassis, and rail transit systems where secure long-term fastening is paramount.
