Lock Washer vs Split Washer – What’s the Difference

Lock Washer vs Split Washer

When you’re ready to begin a project, it can be difficult to determine which type of washers you need. Two of the most common types of washers are lock and split washers. But what exactly is the difference between these two types of washers? In this blog post, we’ll explore the differences between a lock washer and a split washer so you can make an informed decision when purchasing parts for your next project.

What is Lock Washer?

Lock washers are designed to keep screws or bolts from loosening due to vibration or other movement forces. They are made of metal and have a spring-like appearance with teeth around their circumference. These teeth help to grip onto the fastener, thus creating more friction that keeps it in place. For added security, they can also be used with other components, such as nuts and flat washers.

What is Split Washer?

Split washers are also used to secure screws or bolts, but they are much different than lock washers in both design and function. Unlike lock washers, split washers have an open centre hole that allows them to be compressed when tightened down onto the fastener. This compression helps create a tight seal that keeps the fastener from coming loose over time due to vibration or other forces. Split washers are usually made of softer materials like rubber or plastic, making them less likely to damage surfaces they come into contact with.

Difference Between Lock Washer and Split Washer

  • A lock washer is a type of washer that is used to prevent a nut or bolt from loosening.
  • A split washer is a type of washer that is used to distribute the load of a fastener.
  • Lock washers are more effective than split washers at preventing nuts and bolts from loosening.
  • Split washers are less likely to damage the surface around a nut or bolt than lock washers.
  • Lock washers are more expensive than split washers.
  • Split washers are more commonly used than lock washers.


When it comes time for your next project, understanding the difference between lock washers and split washers is essential for finding success during installation. Lock washers provide extra security through teeth that grip onto fasteners, while split washers provide added stability by compressing themselves against surfaces as they’re tightened down. Hopefully, this blog post has given you greater insight into these two types of fasteners so that you can make an informed decision when choosing parts for your next project!
