Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact M40X1.5 thread specification, ensuring correct thread engagement and holding torque for the application.
- Direct OEM Replacement — This ring nut installs directly in place of the original, with no rework or adaptation needed to achieve a proper fit.
- Broad GTH Fitment — Compatible with multiple GTH telehandler variants, including IIIA, IIIB, AU, and R-suffix models across the GTH-4014, GTH-4018, GTH-4016R, GTH-4018R, and GTH-5021 R lines.
- Secure Fastening — A correctly fitted ring nut maintains the integrity of the assembly it secures; a worn, stripped, or incorrect nut can allow movement or loosening that compromises the joint.
- Genuine Genie Part — Sourced directly through authorized Genie OEM supply channels, so you receive the exact part the machine was built with.
A ring nut is a round, externally knurled or spanner-driven fastener threaded onto a shaft, spindle, or bolt to lock a component in position or apply controlled preload to an assembly. At the M40X1.5 thread size, this is a heavy-duty fastener designed for a large-diameter application where correct seating and thread integrity are critical. If the nut is worn, cross-threaded, or missing, the assembly it retains can shift or loosen during operation, leading to accelerated wear or failure of the components it holds. Replacing it with the correct OEM part restores the joint to its original specification.
