Internal Circlips – How to Measure!

Internal Circlips are very easy to measure.

There are two main ways to identify the Circlip you require. Please note the following information is for Internal Circlips only.

  1. If you do not have an existing Internal Circlip with you, simply measure the bore size the Circlip will be fitting in to. All Internal Circlips are listed by the bore size. For example; If your bore measures 30mm, you would need to purchase a 30mm Internal Circlip.
  2. Secondly, if you do have an Internal Circlip to hand, simply measure from the outside edge of one side, to the inside edge of the following side. Measure the Circlip width ways (two lugs at the top). For example; If this measurement comes out at 20mm, you would need a 20mm Internal Circlip.
