What is the difference between a spring washer and a plain washer?

Washers are one of the commonly used fasteners in mechanical engineering and manufacturing. They provide support, disperse pressure and prevent loosening between connecting parts. Let's explore the difference between spring washers and ordinary washers to give you a better understanding of the characteristics and applications of these two washers.

Characteristics of spring washers

Spring washers are usually made of elastic materials and have a certain elasticity and compression capacity. They are designed to provide additional tightening force to prevent bolts and nuts from loosening under vibration or load changes. The shape and structure of spring washers enable them to maintain stability when subjected to force.

Characteristics of ordinary washers

Ordinary washers are generally made of metal or plastic materials and are mainly used to disperse loads and protect the surfaces of connecting parts. Their design is relatively simple, usually flat circular pieces, which can effectively prevent wear and corrosion between connecting parts.

Comparison between spring washers and ordinary washers

In terms of function, there are significant differences between spring washers and ordinary washers. Spring washers are mainly used to prevent loosening, while ordinary washers focus on load dispersion and surface protection. Additionally, spring washers perform better when subjected to vibration and shock, while regular washers are more effective under static loads.

Understanding the difference between spring washers and regular washers is essential for selecting the right fastener. Depending on the specific application requirements, choosing the right washer can improve the stability and security of the connection.
