Description
DIN 137 (A) Curved Spring Washers are specially designed for use in bolted assemblies where flexibility and dynamic load absorption are critical. The curved profile of Type A washers allows for elastic deformation under load, providing excellent resistance to vibration, loosening, and dynamic stress.
Available in carbon steel and stainless steel, these washers come in a wide range of protective finishes such as plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation—each suited to specific environmental and operational conditions.
These washers meet international standards including GB, DIN, ISO, ANSI/ASTM, BS, JIS, and can be customized for non-standard OEM requirements based on drawings or samples. Free samples are available for evaluation.
