Cross-reference part number 7-194-89GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Nylock Locking Element — The nylon insert creates friction against the bolt thread, resisting loosening from vibration and dynamic loads common in telehandler operation.
- 5/16-18 Thread Specification — Sized and threaded to the precise 5/16-18 UNC standard, this nut installs directly without modification to the mating bolt or fastener location.
- Confirmed GTH Telehandler Fitment — Designed for Genie GTH-644, GTH-844, and GTH-842 telehandlers, keeping the replacement process straightforward for technicians familiar with those models.
- Genuine Genie OEM Part — Sourced directly from Genie, this fastener meets the same specification as the hardware originally installed, ensuring dimensional conformity with the mating components.
A jam nut is a thin nut threaded onto a bolt or stud and tightened against a primary nut or component face to lock the assembly in position and prevent unwanted rotation or movement. The Nylock variant adds a nylon insert that grips the thread and provides additional resistance to vibration-induced loosening — an important quality in mobile equipment that experiences constant movement and load cycling. A missing, stripped, or improperly torqued jam nut can allow critical adjustments to shift out of specification, affecting the performance and safety of the fastened assembly. Replacing a worn or damaged jam nut with the correct OEM part restores the fastener stack to its intended configuration.
