Steel External Retaining Ring Assortment (255 Pieces), Black Phosphate Finish, Metric, With Case

The 255-piece steel external retaining ring assortment with black phosphate finish includes external retaining rings in various sizes and comes in a compartmented plastic case for storage and organization. Also known as E-clips, they are designed for positive retention of pulleys, sprockets, springs, and bearings on shafts and rods. The rings are made from steel for strength. The material is magnetic. The black phosphate finish adds corrosion resistance.

Retaining rings attach to a shaft (external) or install in a bore (internal), creating a shoulder to maintain component positioning within an assembly. While most rings install into a machined groove either on the inside or outside diameter of a shaft, self-locking rings attach to a shaft by using friction from means such as teeth and notches to maintain placement. Retaining rings should fit tightly enough into the groove or onto the shaft so they won't experience any movement.
