The Genie 87722GT is a genuine OEM Nylock Nut, 7/8-9 built for Genie RL4 light towers and TZ-34/20 and TZ-50 trailer-mounted articulating boom lifts. As a direct OEM replacement, this nut is manufactured to the same specifications as the original hardware, ensuring proper thread engagement and holding force wherever it is installed on the machine. Cross-reference part number 87722GT against your machine's parts manual to confirm it is the correct fastener for your application before ordering.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Genie's original dimensional and material specifications, delivering the correct thread pitch and clamping force for a 7/8-9 fastener application.
- Nylon Insert Locking Mechanism — The nylon collar grips the thread under vibration and loading, resisting loosening without the need for additional locking hardware.
- Direct OEM Replacement — Matches the original nut in thread size, pitch, and profile, so this nut installs in place of the factory hardware with no modification.
- Broad Genie Fitment — Fits Genie RL4 light towers and TZ-34/20 and TZ-50 trailer-mounted articulating booms, making it a useful fastener to stock for mixed Genie fleets.
- Structural Connection Integrity — A correctly torqued and locked nut holds critical joints secure during machine operation; a loose or failed nut can allow structural movement that compromises performance and safety.
A Nylock nut is a standard hex nut fitted with a nylon insert at the top of the thread. When the bolt is driven through, the nylon deforms around the threads and creates friction that resists the nut backing off under vibration, shock loads, or cyclic stress — conditions common on mobile aerial equipment and light towers. Using the correct OEM nut at the specified thread size ensures the joint achieves its design clamping load; an incorrectly sized or worn fastener can allow joint movement that, over time, damages mating components or causes connection failure.
