Spring Lock Washers are a common form of Washer.

They help with the prevention of fasteners becoming loose during vibration. Spring Lock Washers contain a split so that when tightened each side, they bite into the nut and mounting surface. This helps against any anti-vibration rotation that may occur during vibration.

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

Here are some commonly asked questions on Shakeproof Washers.

Wave Washers, or Wave Spring Washers provide thrust loads and also absorb vibration in applications with little axial space.

These types of Wave Spring Washers are particularly useful for the pre-loading of bearings, for example, in electric motors. The Washers are installed within the bearing housing and operate by maintaining a force on the outer face of the bearing. This ensures a smooth and quiet running of the motor which helps extend the life of the bearing.

The overlap in the Wave Washer allows the end to move during compression.

External Circlips come in a wide range of sizes, starting from as small as 3mm shaft dia.

Need help with installing a Split Cotter Pin correctly?

Here is our helpful guide to provide assistance in ensuring you are using the correct size and installing your split cotter pin correctly.

Here is some helpful information when it comes to fitting Spring Pins, also known as Roll Pins.

Firstly, make sure the spring pin or roll pin is the correct size. These are always listed by the hole size they are fitting in to. For example, a 5mm spring pin, will suit a 5mm hole.

Then make sure the holes in both the Spring Pin, and the hole in your application are aligned accurately so the pin can be inserted smoothly.

Once the pin is aligned to the hole, gently tap the pin in using controlled strikes to avoid misalignment or deformation.

Finally, ensure the pin has a flush fit to the components surface, this will provide a secure connection.
