Product description

The whiz lock nut is a specialized flange nut featuring integrated serrations on its base, designed for use on Coats tire changers. These serrations bite into the mounting surface to provide exceptional resistance to loosening, effectively acting as both a nut and a lock washer in one component. This makes it ideal for securing vibrating panels, pneumatic valves, and internal frame components where maintenance access is difficult. Because the locking action is mechanical, these nuts are often reusable and maintain their grip better than standard lock washers over time. Replacing missing or standard nuts with this whiz lock version is a smart way to enhance the long-term structural stability of your shop equipment.
