Washer kits comprise a variety of different disc-shaped plates with holes. They are typically used to distribute a load of a particular type of threaded fastener, like a [screw or bolt](https://uk.rs-online.com/web/c/fasteners-fixings/screws-bolts/).

Washers have two main purposes:

- To distribute the pressure of a nut evenly to avoid damaging a surface.
- To ensure that the nut is pressed against a smooth surface, reducing the chance of loosening due to it being in contact with an uneven surface.

### Types of washer kits

#### Plain washer kits

This type of washer prevents damage to a surface when it is being fixed. Alternatively, it can act as electrical insulation.

#### Spring washer kits

Spring washers have axial (forming an axis) flexibility and are typically used to prevent fastening or loosening caused by vibration.

#### Locking washer kits

Locking washer kits prevent the unscrewing of the fastening device for improved durability.

#### Domed Cap & Cup Washer kits

Domed cap & cup washer kits are a two-part application. The cup washed is used on a screw or bolt similar to any normal washer, however, its cupped profile provides a small lip for the domed cap to seat over the screw head, around the lip and remain in place to his the screw head.



Washer kits contain various different shaped O-rings that distribute the load of threaded fasteners to minimise wear and avoid loosening of fasteners.
