Washer nut for Terex PT70

The 0090-042 washer nut is a specialized fastening component engineered for the Terex PT70 compact track loader. This nut features a 5/8-11 thread size and incorporates an integrated toplock mechanism designed to create friction on the bolt threads to prevent loosening during operation. It is utilized within the machine assembly, specifically for applications such as the engine subsystem on units with serial numbers DTH 00682 and later.

This component serves to keep critical assemblies firmly connected, ensuring structural integrity throughout the machine. By maintaining a secure fit, the nut helps prevent the separation of parts that may be subject to constant movement or operational stress. The locking design is intended for use in environments where standard fasteners might otherwise back off due to mechanical forces. Proper installation of this nut is necessary to ensure that connections remain fixed in their intended positions.
