context_page_description: A retaining ring is a fastener that holds components or assemblies onto a shaft or in a housing/bore when installed - typically in a groove - for one time use only. Once installed, the exposed portion acts as a shoulder which retains the specific component or assembly. Circlips are a type of retaining ring.
  Circular push-on retaining rings may be installed in applications where there is no groove.
  Retaining rings are typically made from carbon steel, stainless steel or beryllium copper and may feature a variety of finishes for aesthetics and corrosion protection depending on the type of environment in which they are used.
context_section_description: Spiral retaining rings are axially installed into housings/bores (internal) or onto shafts (external), making 360° contact with the groove.  Spiral retaining rings have no ears or lugs to interfere with the assembly. These rings are manufactured by coiling flat wire into the shape of the finished retaining ring. Spiral rings are provided with a removal notch to simplify the removal process.  Spiral retaining rings can be economically produced in special alloys like stainless steel because the manufacturing process eliminates scrap.
  No special tools are required for installation or removal.  Duck billed pliers can be used in installing and removing external spiral rings.
