The Genie 110878GT is a genuine OEM Nylock Nut, 5/8-11, Gr.8 built for Genie GS scissor lifts and Z-series articulating boom lifts. As a Genie OEM part, this nut is manufactured to the same dimensional and material standards as the hardware originally installed at the factory, ensuring a consistent fit on every application. It is confirmed for use on the GS-3384, GS-3390, GS-4390, and GS-5390 scissor lifts, as well as the Z-40/23N and Z-40/23N RJ articulating boom lifts. When replacing fasteners on critical assemblies, sourcing the correct grade and thread specification matters — cross-reference part number 110878GT against your machine's parts manual before ordering.
Key Features
- Grade 8 Material Strength — Manufactured to Grade 8 specification, providing the tensile strength required for structural and load-bearing fastener positions on Genie equipment.
- Nylon Insert Locking — The nylon collar grips the mating thread and resists loosening under vibration, maintaining joint integrity throughout the service cycle.
- Correct Thread Form — Cut to a 5/8-11 UNC thread pitch, this nut seats and torques properly on matching bolts without rework or thread chasing.
- Broad Model Coverage — Fits multiple Genie GS scissor lift models and Z-40/23N articulating boom lift variants, making it a practical stocking item for mixed Genie fleets.
- Genuine OEM Consistency — Supplied as a genuine Genie OEM part, so the grade marking, dimensions, and nylon insert grade match the original hardware specification exactly.
A Nylock nut uses a nylon insert at the top of the nut to create friction against the bolt thread, preventing the fastener from backing out due to vibration or dynamic loading — conditions common on aerial lifts that travel over uneven ground and extend under load. On Genie GS scissor lifts and Z-series boom lifts, fasteners in structural pivot points, platform connections, and chassis assemblies are subject to continuous movement and stress. A Nylock nut that has lost its locking effectiveness — because the nylon insert is worn, the nut has been over-torqued, or a standard nut has been substituted in its place — can work loose over time, leading to joint movement and potential structural failure. Replacing worn or damaged fasteners with the correct Grade 8 Nylock Nut, 5/8-11 keeps those connections secure and maintains the integrity of the assembly.
