Washers are small, circular discs with a hole in the center that are used in conjunction with bolts and screws. They serve a variety of purposes, such as distributing load, providing spacing, and protecting surfaces. While it may seem like a small and insignificant component, using a washer on a bolt can make a big difference in the performance, stability, and safety of your project. In this article, we’ll explore when and why you should use a washer on a bolt, and provide tips for selecting the right washer for your application.
Why Use a Washer on a Bolt?
There are several reasons why you should use a washer on a bolt, including:
Distribution of load: Washers are used to distribute the load on a bolt, helping to prevent concentration of stress and strain on a single point. This can reduce the likelihood of bolt failure and improve the overall stability of the project.
Spacing: Washers are used to provide spacing between components, helping to prevent binding and other issues. This can improve the performance and functionality of the project.
Protection of surfaces: Washers are used to protect surfaces from damage, such as scratching, marring, or indentation. This can be especially important in applications where the appearance or integrity of the surface is important.
Corrosion protection: Washers can help to prevent corrosion by providing a barrier between the bolt and the surface being fastened. This can improve the longevity and performance of the project.
When to Use a Washer on a Bolt
There are several situations in which you should use a washer on a bolt, including:
Heavy loads or high stress: If your project involves heavy loads or high stress, using a washer can help to distribute the load and reduce the risk of bolt failure.
Protecting surfaces: If your project involves fastening components to surfaces that are prone to damage, such as painted or finished surfaces, using a washer can help to protect the surface from scratching or marring.
Spacing: If your project requires spacing between components, using a washer can help to provide the necessary spacing and prevent binding or other issues.
Corrosion protection: If your project involves fastening components in a corrosive environment, using a washer can help to prevent corrosion and improve the longevity of the project.
Tips for Selecting the Right Washer
When selecting a washer bolt for your project, it’s important to consider the following factors:
Load-bearing capacity: If your project involves heavy loads or high stress, you’ll want to choose a washer that is strong and durable, such as a fender washer. Flat washers are not suitable for use in high-stress or load-bearing applications.
Hole size: The hole size in the center of the washer should match the diameter of the bolt or screw being used. Using a washer with a hole size that is too small or too large can cause problems with fit and performance.
Material: The material of the washer is also important to consider. Different materials have different properties and characteristics, such as corrosion resistance, electrical conductivity, and more. Choose a material that is suitable for your application and environment.
Cost: Consider your budget when selecting a washer. Fender washers are generally more expensive than flat washers, so you’ll want to consider whether the added cost is justified for your project.
In conclusion, using a washer on a bolt can improve the performance, stability, and safety of your project. Consider using a washer when working with heavy loads or high stress, protecting surfaces, providing spacing, or preventing corrosion. When selecting a washer, consider factors such as load-bearing capacity, hole size, material, and cost. By taking the time to choose the right washer for your application, you can ensure that your project is successful and performs to its full potential.
