What is the difference between Snap Rings & Circlips?

One of the most common questions we are asked, is what is the difference between Snap Rings and Circlips…

This has a very simple answer.

Circlips (or retaining rings) have lugs with holes, so that they can be inserted on to the shaft or bore with pliers. The lugs allow the plier to either expand or compress the circlip during installation.

Snap Rings do not contain lugs, and offer a smooth all round continuous form without the protrusion of lugs which could interfere with applications. These can be inserted by using flat screwdrivers.

External Circlips (with lugs) form the ‘1400’ series

Internal Circlips (with lugs) form the ‘1300’ series

External Snap Rings (without lugs) form the ‘M2400’ series

Internal Snap Rings (without lugs) form the ‘M2300’ series
