Measuring Internal Circlips could not be easier…

Internal Circlips are always listed by the BORE size they’re fitting in to. For example, we list a 10mm Internal Circlip, this will suit a bore size of 10mm, with a groove of 10.4mm.

Alternatively, measure from the outside edge of the widest part of the Internal Circlip, to the inside edge on the opposite size. This will also indicate the size of Circlip you need. For example, if this measures 30,, you will need a 30mm Internal Circlip. PLEASE NOTE! This method of measuring only applies to DIN 472 Metric Circlips and not Imperial sizes.

We are always on hand to help with technical advice in finding the right circlip for you. Call us today on 0121 661 6664 or email us: sales@calebcomponents.com

Shakeproof Washers can be made as External Types or Internal Types depending on application.

Shakeproof Washers contain a serrated edge which enables is to be held in place by biting into the surface. They are used in applications where there are fastenings with a larger head which will resist the force of the washer being compressed as well as holding the surface.

These Washers can also be known as Tooth Locking Washers. They are most commonly finished in a bright zinc plate for corrosion resistance.
