Washer

Washers are used to distribute the load from a bolt or other fastener over a larger area. This helps to prevent the fastener from damaging the material it is being used to fasten.

Washers come in a variety of shapes and sizes, depending on the application. The most common type of washer is the flat washer. Flat washers have a flat surface that distributes the load over a larger area.

Other common types of washers include:

Spring washers: Spring washers have a spring-like shape that helps to hold the fastener in place.

Lock washers: Lock washers have a serrated or knurled surface that helps to prevent the fastener from loosening.

Felt washers: Felt washers are used to provide a cushion between the fastener and the material it is being used to fasten.

Washers are used in a variety of applications, including:

Fastening furniture together

Securing electrical components

Attaching hardware to walls

Mounting equipment

Joining metal parts

Washers are an essential part of many different types of products and structures. They help to ensure that fasteners are properly installed and that the loads they are subjected to are evenly distributed.

Here are some of the specifications and standards for washers:

Thread size: The thread size of a washer is the same as the thread size of the fastener it is being used with.

Diameter: The diameter of a washer is the distance across the flat surface of the washer.

Thickness: The thickness of a washer is the distance from the top of the washer to the bottom.

Material: Washers are typically made of metal, but can also be made of plastic or other materials.

The choice of washer material depends on the application and the specific requirements of the project.
