Choosing the Right Split Washer: Types, Materials, and Applications

A split washer, also known as a spring washer, is designed to eliminate vibration and provide a more secure joint between two surfaces. Choosing the right split washer for your application can be daunting, with so many types and materials available. In this blog post, we’ll explore the different types of split washers, the materials they are made of and their applications. By the end of this post, you will better understand how to choose the right split washer and ensure a secure joint.

What is a Split Washer?

Split washers, also known as spring washers, are hardware used in various applications to prevent loosening or shifting components due to vibration or motion. They consist of a circular washer with a split on one side, allowing it to compress when tightened.

One may wonder why such a simple device is necessary in the first place. The answer lies in the fundamental physics behind fasteners and their ability to maintain tension. When two components are fastened together, some force will always be acting on them that tries to separate them. This can be caused by external forces such as vibrations from machinery or internal forces like thermal expansion.

Types, Materials, and Applications of Split Washers

Types of Split Washers:

There are three main types of split washers: helical, toothed, and wave. Helical split washers are the most common type, with a spiral design that provides a spring-like action to resist loosening. On the other hand, toothed split washers have teeth around their circumference to grip the bolt and prevent it from coming loose. Wave split washers have a wave shape that creates a spring-like action and absorbs vibration, making them ideal for high-vibration applications.

Materials of Split Washers:

Split washers can be made of various materials, including stainless steel, brass, bronze, and plastic. Stainless steel is the most popular material for split washers as it is corrosion-resistant and durable. Brass and bronze split washers are corrosion-resistant but less strong than stainless steel. Plastic split washers are used in applications where electrical insulation is required.

Applications of Split Washers:

Split washers can be used in various automotive, industrial, and construction applications. They are commonly used in high-vibration applications, such as engines and heavy machinery. Split washers can also be used in electrical applications where the washer needs to be insulated from electrical contact.

How to Choose the Right Split Washer?

When choosing a split washer, you should consider the application, the size of the bolt, and the materials being joined. Helical split washers are a good choice for low to medium-vibration applications, while toothed split washers are better suited for applications with high vibration. Wave split washers are ideal for applications with extreme vibration. Stainless steel split washers are the most common choice for most applications due to their durability and corrosion resistance.

Conclusion:

Choosing the right split washer for your application ensures a secure joint. You can make an informed decision by understanding the different types of split washers, the materials they are made of, and their applications. Helical split washers, toothed split washers, and wave split washers are the three main types of split washers. Stainless steel is the most popular material for split washers due to its durability and corrosion resistance. When choosing a split washer, consider the application, the bolt size, and the materials being joined to ensure you choose the right split washer for your needs.
