C Clip Retaining Ring DIN 471 Metal Circlips Standard Circlip Manufacturer

C clip retaining ring is a type of fastener or retaining ring consisting of a semi-flexible metal ring with open ends which can be snapped into place, into a machined groove on a dowel pin or other part to permit rotation but to prevent lateral movement. There are two basic types: internal and external, referring to whether they are fitted into a bore or over a shaft. Circlips are often used to secure pinned connections. When used to retain piston wrist pins (US) / gudgeon pins (UK), the clips are known as wrist pin clips or wrist pin retainers (US) or gudgeon pin clips (UK). The most commonly used circlip for this application is a simple spring steel circlip (snap ring US), or plain wire ring. Ever Hardware provides custom-made fasteners and customizable packaging.
Common examples include e-clips (e-ring) and the (both internal and external) snap ring (US) or circlip (UK). These general types of fasteners are sized to provide an interference fit onto (or into, in the case of an internal fastener) a groove or land when in use, such that they must be elastically deformed in order to install or remove them.

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.
