Metric External Retaining Rings are unthreaded fasteners used to hold a round shaft in place in an assembly or to locate components in place on a shaft.

DIN 471 External Retaining Rings are installed into a groove on a shaft with the use of retaining ring pliers. Part of the retaining ring remains exposed outside of the groove and acts as a stop to hold the assembly in place.

Metric & Multistandard Components Corp. can supply Din 471 External Retaining Rings in steel and stainless steel.
