DIN 471 Circlips Washers are also known as retaining rings which is a fastener that holds components or assemblies onto a shaft or in a housing/bore when installed in a groove. Once installed, the exposed portion acts as a shoulder which retains the specific component or assembly. DIN 471 Circlips Washers or DIN 471 Retaining Rings are typically made from carbon steel, stainless steel or beryllium copper and may feature a variety of finishes for corrosion protection depending on the type of environment in which they are used. DIN 471 Circlips Washers or DIN 471 Retaining Rings are available in various types including DIN 471 Tapered Section Circlips, DIN 471 Constant Section Circlips and DIN 471 Spiral Circlips.
