Don’t worry; it’s not as complicated as it sounds! Installing a star lock washer is an easy way to secure fasteners and help prevent them from loosening due to vibration. This guide will provide step-by-step instructions on properly installing a star lock washer.
Why Do You Use the Star Lock Washer?
Star lock washers, also known as star washers or internal/external tooth washers, are used to help prevent nuts, bolts, or screws from becoming loose due to vibration or torque.
The teeth or points on the outer circumference of the washer create friction when the nut or bolt is tightened, allowing them to stay firmly in place and secure the assembly.
How to Select the Right Size?
To select the correct star lock washer for a particular nut size, you’ll need to determine the outer diameter (OD) of the washer that fits the bolt or screw. The OD of the washer should match the nut or bolt head size. For example, if you have a 1/2-inch nut, you’ll need a star lock washer with an OD of 1/2 inch.

The Proper Way to Install a Star Lock Washer
Installing a star lock washer is a simple process that can be completed in just a few steps. Here’s a step-by-step guide to help you properly install a star lock washer:
Step 1 – Choose Right Washer
Choosing the right size of star lock washer is essential. An easy way to do this is to select a washer the same size as the nut. Manufacturers typically make star lock washers in sizes that match the nuts intended to secure.
Step 2 – Place the Washer
Once you have selected the correct size star lock washer, place it onto the nut or bolt before tightening. Make sure that the teeth or points on the outer circumference of the washer are facing toward the surface you are tightening against.
Step 3 – Tighten the Nut or Bolt
After placing the star lock washer onto the nut or bolt, tighten the nut or bolt using the wrench or other appropriate tool. The teeth or points on the outer circumference of the washer will dig into the surface and create friction.
Step 4 – Check Tightness
Once the nut or bolt is tightened, check the tightness by attempting to turn it counterclockwise with a wrench or socket. If there is no movement or looseness, the star lock washer has been properly installed and is doing its job.
In case of any movement or looseness, recheck the installation, ensure the washer is properly seated on the surface, and ensure the nuts or bolts are tightened to the correct torque specification.
And that’s it! You have successfully installed a star lock washer.
