Washers are flat, circular parts, often made from materials such as metal, plastic, or rubber. They are used to distribute the load of a bolt or screw over a larger area to prevent damage.
There are several types of washers, including:
Flat washers: the most common, they have a flat, uniform surface.
Security washers: also called Grower or Belleville washers, they have a conical shape and are used to provide constant clamping pressure.
Spring washers: also called spring washers, they are compressible and are often used to compensate for pressure variations or to prevent leaks.
Wave washers: also called serrated washers, they are used to prevent nuts from loosening.
Friction washers: also called locking washers, they have a rough surface that creates additional friction to prevent loosening. Washers are often used in conjunction with nuts and bolts to create strong and secure assemblies. Choosing the correct size and type of washer for each application is crucial to ensuring the assembly's safety and reliability.
