Stainless Steel Circlips

Quality Stainless Steel Circlips Available From UK Stock

M Barnwell Services is one of the UK’s largest independent stockist and distributor of Internal and External Stainless Steel Circlips, Crescent Rings, Retaining Rings and Fasteners.

We understand that applications can require a Circlip material that is superior to the standard carbon spring steel (CS). Stainless steel is an excellent alternative as it does not easily rust, corrode or stain with water like uncoated carbon steel, and still retains its strength. These qualities make it an invaluable product to industries such as Offshore Drilling, Aerospace and Defence, Automotive, and Petrochemical.


The benefits of an M Barnwell Services Stainless Steel Circlip:

  • High resistance to corrosion
    Stainless Steel performs excellently when the application is exposed to highly corrosive environments such as seawater
  • Intense heat resistance
    If the application is exposed to intense heat, Stainless Steel has increased resistance to damage, deformity, and also has a higher melting threshold
  • Aesthetics
    The reflective quality of Stainless Steel will help it blend into the application. Our Stainless Steel Circlips are easy to clean and do not fade or discolour over time
  • High stock levels
    5mm to 130mm, available in Grade 420
  • Packing and bagging service
    M Barnwell Services also offers a bespoke kit labelling service. Visit the Kit Branding and Packaging page for more information.
