Hey there! I’m a supplier of spring washers, and I often get asked about the difference between spring washers and wave washers. In this blog, I’ll break down the key distinctions, so you can make the right choice for your projects. Spring Washers<\/a><\/p>\n

<\/p>\n

What are Spring Washers?<\/h3>\n

Let’s start with spring washers. These guys are pretty common in the fastener world. A spring washer, also known as a helical spring washer, is designed to provide a certain degree of spring tension when compressed between a nut and a surface or between two mating parts.<\/p>\n

The most common type of spring washer is the split – lock washer. It has a split in it, and when you tighten the nut or bolt, the sharp edges of the split dig into the surface they’re in contact with. This creates friction, which helps prevent the fastener from loosening due to vibrations.<\/p>\n

Spring washers are made from various materials, like steel, stainless steel, and brass. Steel spring washers are strong and durable, making them suitable for heavy – duty applications. Stainless steel ones are corrosion – resistant, so they’re great for outdoor or wet environments. Brass spring washers are often used in electrical applications because of their good conductivity.<\/p>\n

One of the main advantages of spring washers is their ability to maintain a constant preload. When you tighten a bolt or nut, the spring washer compresses and stores energy. This stored energy continuously applies a force on the fastener, keeping it tight even when there are external factors like vibrations or thermal expansion.<\/p>\n

What are Wave Washers?<\/h3>\n

Now, let’s talk about wave washers. Wave washers are flat washers with a wave – like shape. They have multiple undulations or waves around their circumference. This unique shape gives them some specific properties.<\/p>\n

Wave washers are mainly used for applications where a low – height spring force is required. Because of their wave design, they can provide a spring action in a relatively thin space. They’re often used in tight spaces where a regular spring washer might be too thick.<\/p>\n

Like spring washers, wave washers are also made from different materials. Steel wave washers are commonly used for general – purpose applications. They can handle moderate loads and offer good spring characteristics. For applications where corrosion is a concern, stainless steel wave washers are a popular choice. And in some cases, plastic wave washers are used for their lightweight and electrical insulation properties.<\/p>\n

One key feature of wave washers is their ability to provide a relatively uniform load distribution. The waves help spread the force evenly across the contact surface, which is useful in applications where you need to prevent damage to the mating parts.<\/p>\n

Key Differences<\/h3>\n

Shape<\/h4>\n

The most obvious difference between spring washers and wave washers is their shape. Spring washers, especially the split – lock type, have a split in a circular shape, and they might look like a coiled spring cut in half. On the other hand, wave washers have a flat profile with waves around their edge. This shape difference affects how they’re used and the kind of forces they can provide.<\/p>\n

Spring Force<\/h4>\n

Spring washers are designed to provide a relatively high spring force. They’re used in applications where you need to keep a bolt or nut tightly secured, even under high – vibration conditions. The compression of the split – lock washer creates a significant amount of friction and preload.<\/p>\n

Wave washers, however, are better suited for applications where a lower spring force is needed. The wave shape allows them to provide a more gentle, but still effective, spring action. They’re often used in precision mechanisms where you don’t want to overload the components.<\/p>\n

Space Requirements<\/h4>\n

Spring washers can be relatively thick, especially if you’re using a large – sized one. This means they need more space between the nut and the surface. In contrast, wave washers are much thinner in profile. They can be used in tight spaces like inside small electronic devices or in machinery where space is at a premium.<\/p>\n

Load Distribution<\/h4>\n

Spring washers, particularly split – lock washers, tend to concentrate the load at the points where the split edges contact the surface. This can be a disadvantage in some applications where you want to avoid damage to the mating parts. Wave washers, with their wave – like shape, distribute the load more evenly across the contact area. This makes them a better choice for applications where you need to protect the surface of the components.<\/p>\n
