What are the different types of lock washers?

Hey there! As a supplier of lock washers, I've seen firsthand how these little components play a huge role in various industries. Lock washers are essential for preventing nuts and bolts from loosening due to vibration, rotation, or other external forces. In this blog, I'm gonna walk you through the different types of lock washers out there.

Spring Lock Washers

Spring lock washers are probably the most well - known type. They're designed to provide a spring tension between the nut or bolt head and the surface it's fastened against. This tension helps keep the fastener in place by counteracting the forces that could cause it to come loose.

There are a couple of subtypes of spring lock washers. One is the helical spring lock washer. It has a coiled shape that wraps around the fastener. The sharp edges of this washer dig into the surface, creating additional friction to hold things tight.

Another common subtype is the wave spring lock washer. This one has a wavy shape. When you tighten the fastener, the waves compress, and they push back with a spring force. This force helps maintain the clamping pressure, which is crucial for keeping the joint secure.

Toothed Lock Washers

Toothed lock washers have teeth that bite into the surfaces they're in contact with. There are two main types: external and internal serrated lock washers.

The Internal Serrated Lock Washer has teeth on the inside diameter. When you install it, these teeth grip the bolt or screw, preventing it from rotating. This type of washer is great for applications where you want to keep the fastener from turning relative to the part it's attached to.

External serrated lock washers, on the other hand, have teeth on the outside diameter. They dig into the surface of the material being fastened, providing a high - level of resistance against loosening. These are often used in applications where the base material is soft or where there's a lot of vibration.

Split Lock Washers

Split lock washers are simple yet effective. They're made from a flat piece of metal that's cut and twisted to form a split. When the nut or bolt is tightened, the split washer gets compressed. The ends of the split push against each other, creating a spring - like force. This force adds extra tension to the fastener, helping to prevent it from backing out.

One thing to note about split lock washers is that they work best in applications with relatively low vibration. In high - vibration scenarios, they might not be as effective as some of the other types of lock washers.

Belleville Washers

Belleville washers, also known as conical spring washers, are shaped like cones. They can be stacked in different configurations to achieve different levels of spring force. When a load is applied, the cone shape flattens out slightly, and it stores energy in the form of spring tension.

Belleville washers are great for applications where you need a high load capacity in a small space. They're often used in heavy - duty machinery, automotive engines, and aerospace applications.

Butterfly Lock Washers

The Butterfly Lock Washer is a unique type. It has a distinct butterfly - like shape. The curved arms of the washer provide a spring force when compressed. This spring force helps keep the fastener tight.

These washers are often used in applications where there's a need for a visual indication of proper installation. The shape also makes them relatively easy to handle and install by hand.

Double Fold Wedge Lock Washers

Double Fold Wedge Lock Washers are designed to provide a very high level of resistance to loosening. They have a double - fold design that creates a wedge effect. When the fastener is tightened, the wedges dig into the surfaces, locking the fastener in place.

These washers are ideal for high - vibration and high - torque applications. They're commonly used in the construction, automotive, and manufacturing industries.

Choosing the Right Lock Washer

Now that you know about the different types of lock washers, how do you choose the right one for your application? Well, it depends on a few factors.

First, consider the level of vibration in your application. If there's a lot of vibration, you'll probably want to go with a more heavy - duty option like a double fold wedge lock washer or a toothed lock washer. For low - vibration applications, a split lock washer or a wave spring lock washer might do the trick.

Next, think about the load capacity. If you need to hold a heavy load, a Belleville washer or a double fold wedge lock washer could be a good choice.

The type of material you're working with also matters. If the material is soft, an external serrated lock washer can help prevent the washer from sinking into the material.
