This nylon lock nut is commonly used to secure blades, wheels, and other critical components on lawn mowers, tractors, and various outdoor power equipment. The nylon insert creates friction against the bolt threads, preventing the nut from backing off due to vibration. Always replace lock nuts rather than reusing them to ensure proper locking function and safe equipment operation.
