Nylon lock nut for Terex BT4792

The nylon lock nut, part number 221-00032-2, serves as a specialized fastening component for heavy machinery. It is designed with a 5/16-18 thread specification and a zinc coating for corrosion protection. The integrated nylon insert deforms against the bolt threads during installation to provide resistance against loosening in operational environments.

This component is compatible with the Terex BT4792 crane. It is used in various assembly points where secure fastening is required for maintenance and operational integrity. The part is produced by Terex.

Lock nuts of this type are commonly employed in mechanical systems to maintain tension in bolted joints. The nylon insert creates friction that prevents the nut from backing off due to external forces, ensuring that critical connections remain tight during machine operation.
