Stainless Steel Circlips Both DIN 471 & DIN 472 are available is stainless steel grade 304 as standard grade 316 is not commonly available.
Circlips also known as a C-Clips, Seeger rings or Snap rings are 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 allow rotation but to stop 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.
Since circlips are stamped out of sheet metal there is a smooth side and a rough side. To prevent potential damage, circlips are installed with the smooth side facing the part and the rough side facing out. Wet or dry lubrication is required for the circlip to maintain its function.
Circlips are designed to be removed with special circlip pliers (snap ring tool) which can be reassembled for internal or external clips
