Cir Clip DIN 471 External Retaining Ring Clips High Strength Black Oxide

Cir clip is also known as circlip. Circlips are a type of retaining ring. Self-locking 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 corrosion protection depending on the type of environment in which they are used. Ever Hardware provides custom-made fasteners and customizable packaging.
Tapered section retaining rings decrease symmetrically from the center to the free ends, remaining circular when contracted or expanded within the limits of normal use. This assures contact with the groove along the entire periphery of the ring. These rings may be installed axially (horizontally along with the center point of an axis) or radially (externally along the radius of a circle). Depending on the size of the ring in question, it may be manufactured in one of two ways:
For smaller rings: using a die and stamping on a press from a coil of steel or copper
For larger rings: wire forming, in which rectangular wire is coiled into the shape of the ring.

Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper-based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. To achieve maximum corrosion resistance the black oxide must be impregnated with oil or wax. One of its advantages over other coatings is its minimal buildup.
