Detailed explanation of washers materials, classification and uses

stainless steel washers

1. Definition and types of washers

Washers are commonly used parts in fasteners, which have the functions of dispersing locking force, protecting the surface of the connection from damage, and compensating for looseness.

In mechanical manufacturing, washers are a commonly used connection part. It is usually made of metal or non-metallic materials and is used to fill the gap between the connecting bolts and nuts to increase the connection strength and tightening force. Whether in manufacturing, repairing machinery, or DIY enthusiasts, washers play a very important role.

2.Material and size of washers

The materials of washers mainly include metal, rubber, plastic, fiber, etc., among which metal washers are the most widely used. Metal washers can be divided into various types such as steel, stainless steel, copper, aluminum, iron, etc. according to different materials.

The sizes of washers are also varied, and the common parameters are inner diameter, outer diameter, thickness, etc. They are manufactured according to the standards of different countries or user needs.

3. Purpose of washers

Washers are commonly used in the following situations:

  • Insufficient tightening force of fasteners.
  •  Uneven fastening surface.
  •  Looseness or vibration between fasteners.
  • .Prevent corrosion and wear.

4. Classification of washers

Depending on the material, washers can be divided into metal washers, rubber washers, plastic washers, fiber washers and other types.
