Nylok nut for Terex PT30

The 8040-366 Nylok nut is a fastening component designed for the radiator and oil cooler assembly on the Terex PT30 compact track loader, specifically for units with serial numbers DTA 05001 and later. This hardware features a 1/4-20 UNC thread specification and includes an integrated nylon insert that acts as a locking mechanism.

By creating resistance during installation, the nylon insert prevents the nut from loosening due to the mechanical vibrations and thermal cycles typically found within the engine compartment. This secure fastening ensures the stability of the cooling system components, which helps maintain the integrity of the radiator and oil cooler connections during machine operation.

Nylok nuts are commonly used in heavy machinery to maintain torque on threaded fasteners in areas subject to constant movement. The locking insert provides a secure hold without the need for additional locking washers or adhesives, ensuring that the assembly remains tight throughout the service life of the machine.
