The Genie 990150GT Nylock Nut, 1/4-20 GR2 is a genuine OEM fastener built for Genie AL4000, AL5000, and RL4 light towers. As a direct OEM replacement, this nut matches the exact thread specification and grade of the original hardware, ensuring a correct, secure fit without rework or adaptation. Sourced directly from Genie, part number 990150GT is the right choice when restoring fastener integrity on these light tower models.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to Grade 2 specification with the correct 1/4-20 thread form, delivering the dimensional conformity and material grade Genie specifies for this application.
- Nylon-Insert Locking Retention — The nylon locking collar resists vibration-induced loosening, keeping fastened assemblies secure through the operational demands of jobsite equipment.
- Exact Thread Compatibility — The 1/4-20 UNC thread matches the mating fastener hardware on the original assembly, so this nut threads on cleanly with no chasing or modification.
- Confirmed Fitment for Genie Light Towers — Fits AL4000, AL5000, and RL4 light towers, so you can order with confidence knowing this is the correct OEM part for your machine.
- Genuine Genie OEM Part — Supplied as an authentic Genie replacement, this nut meets the same standards as the hardware originally installed at the factory.
A Nylock nut uses a nylon insert embedded in the top of the nut to create friction against the bolt threads, preventing the nut from backing off under vibration or dynamic loading. On light tower equipment — where engine vibration and transport movement are constant — fasteners that work loose can compromise structural assemblies and panel retention. Replacing a worn or missing nut with the correct GR2 1/4-20 Nylock, such as this Genie 990150GT, restores the holding force the assembly was designed around and keeps the connection secure over time.
