Internal Circlips are designed to be fitted into bores with grooves. An Internal Circlip is always listed by the bore size they’re fitting into.

For example, if you require a Circlip to fit into a 50mm bore, you would need to order a 50mm Internal Circlip. Alternatively you can measure the OUTSIDE diameter and find the Circlip you need by looking at our technical information on our website.

Our Internal Circlips are available online in carbon steel and stainless steel. Explore the range here: https://springfasteners.co.uk/product-category/circlips/
