Washers

Washers :

A washer is a thin plate & most commonly has a disk-shape with a hole in middle. In addition, Washers are also used for locking a device and reducing the vibration. These locking washers are available in various types such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.

Here are some common types of washers:

Flat Washers: These are the most basic type of washer and have a flat, circular shape. They are used to distribute the load of a fastener and prevent it from damaging the surface. Flat washers are available in various sizes and materials.

Split Lock Washers: These washers have a split or helical cut and are used to prevent nuts and bolts from loosening due to vibrations. When tightened, the split lock washer exerts spring-like tension to resist rotation.

Lock Washers: Similar to split lock washers, these washers are designed to prevent loosening of fasteners. They often have teeth or external grooves that bite into the material, providing additional resistance to rotation.

Spring Washers: Also known as Belleville washers, these are conical in shape and provide a spring-like action. They are used to maintain tension or compensate for thermal expansion and contraction.

Wave Washers: These washers have a wavy or corrugated shape, providing spring-like flexibility. They are used to absorb shock, reduce vibration, or compensate for variations in tolerances.

Fender Washers: Fender washers have a larger outer diameter compared to standard washers. They are often used in applications where a larger bearing surface is needed to prevent pull-through or to provide additional support.

Square Washers: Square washers have a square shape and are used to prevent rotation of a fastener. They fit into square holes or can be used with square-headed bolts or nuts.

Finish Washers: Also called trim washers, these washers have a decorative finish and are used in applications where appearance is important.

Washers are essential components in many fastening applications, contributing to the stability, longevity, and performance of assemblies. It's important to select the appropriate type and size of washer based on the specific requirements of the application and the type of fastener being used.
