What Are Spring Washers?

As fasteners are used to create secure holds across a myriad of industries, it is important to understand that not all fastening components are created equal. With applications ranging from aviation to manufacturing, and much more, fasteners are available in a vast array of designs with slightly different functions. Although some fasteners may be used on their own, others should be used in tandem with a washer for optimal performance. Washers are disc-shaped parts intended to be used with nuts and bolts, screws, and other fasteners that can pass through the washer’s central hole. For your better knowledge, this blog will examine a particular type of washer known as a spring washer and its unique characteristics.

A spring washer is different from a plain washer in its shape; rather than having a flat outer rim, a spring washer has a curved, or conical, shape. While both plain washers and spring washers work to distribute the load of a fastener over increased surface areas, often a nut and bolt assembly, a spring washer is a smarter choice for applications where there are a lot of vibrations. This is because the curved shape of spring washers prevents them from resting flush against the surface of a machine or object. As such, if the assembly vibrates during operation, a spring washer will be less likely to become loose as a result.

During use, a bolt is inserted through the washer, an object that requires fastening, and a nut, to create a steady bond. The load of the machinery or other object is then placed on the bolt, that of which has a head with a relatively small surface area.The washer works to disperse this load over a greater surface area; However, plain washers are susceptible to any vibrations that occur during operation. Spring washers prevent this from happening by providing an axial load.

Depending on the specific application, different types of spring washers may be used. While none are flat like a plain washer, spring washers are available in various shapes. For example, conical spring washers simply imitate a cone, narrowing toward the middle, while helical spring washers take the form of an open ring with end points on two different planes. Furthermore, some spring washers are ribbed for better gripping purposes, while others may be custom designed for special purposes.
