This M40 external circlip is manufactured to DIN 471 in stainless steel. DIN 471 specifies a sprung retaining ring that sits in a machined groove on a shaft, for locating components axially. The ring springs into a turned groove and forms a shoulder that stops bearings, gears, or collars sliding along the shaft, without the machining a fixed shoulder would need.

Typical applications

  • Retaining bearings, gears, and pulleys on shafts
  • Axial location in gearboxes and drives
  • Machine build and rebuild work
  • Maintenance of rotating assemblies

Available in packs of 10 to 50, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.

How do I choose between A2 and A4 stainless steel?

A2 (304) stainless steel suits most indoor, outdoor and workshop jobs. Choose A4 (316) marine grade for coastal, marine, poolside or other chloride-rich environments.

How do I make sure I order the right size?

Check the size in the product title and the standard, material and dimensions in the Product Specification tab. In M8 x 30, M8 is the thread diameter and 30 is the length in millimetres. See our size guide if you need more help.
