While they may seem fragile at first sight, wave washers and spring washers serve a useful purpose in construction. When you are handling softer material and need a way to create tension with your screw without damaging the material you are securing, wave spring washers can generate the tension you are looking for. There are a variety of these types of washers to choose from. Knowing the difference between each kind can help you select the right tool for your project.

Wave Washer

A typical wave washer looks much like a normal washer that has been bent in the axial direction. This allows the washer to provide additional pressure when being screwed down. They are also a less effective choice as a lock washer. Overall, these washers produce a decent amount of pressure, though not as much as a conical washer.

Conical Washer

A conical washer is also sometimes called a cupped spring washer or Belleville washer. It has a cupped shape, allowing it to provide more pressure than a typical wave washer when it is compressed.

Curved Disc 

At first glance, a curved disc spring looks a lot like a conical washer. This spring only allows for four points of contact, however. It is best used for lighter duty jobs.

Split Washer

Also known as a spring lock washer, a split washer can look like a broken washer at first, but the break serves an important purpose. The spring is twisted into a helical shape, which allows it to exert force on both the screw and the material or substrate.

Use the Right Tool for the Right Job

No matter what type of wave washers or spring washers may be your favorite, it is most important to select the right tool for the right job. Keep in mind that some spring washers are designed better for light-duty applications. Research your material options well to make sure you pick the right washer for your project.
