The Genie 6178GT is a genuine OEM Nylock Nut, 10-32 designed for a wide range of Genie aerial lifts, light towers, and personnel lift equipment. Sourced directly from Genie, this fastener delivers an exact fit across GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, TZ and TMZ trailer-mounted booms, GTH telehandlers, TML and AL light towers, and vertical mast and push-around personnel lift lines including GR, QS, AWP, and DPL models. Cross-reference part number 6178GT against your machine's parts manual to confirm fitment before ordering. As a genuine OEM component, it meets the same specification as the hardware installed at the factory.
Key Features
- Nylon-Insert Locking Thread: The nylon collar grips the mating thread and resists loosening under vibration — critical for fasteners on mobile aerial equipment subject to constant movement and load cycles.
- Genuine OEM Specification: Manufactured to Genie's original thread and dimensional spec for the 10-32 thread size, ensuring correct torque engagement and seating depth on first installation.
- Broad Fleet Coverage: Fits Genie GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, TZ and TMZ trailer booms, GTH telehandlers, AL and TML light towers, and GR, QS, AWP, and DPL personnel lifts — one part number spans a large mixed fleet.
- Direct Drop-In Replacement: Matches the original hex profile and thread engagement length so this nut installs without reworking or re-tapping the mating fastener.
- Structural Fastener Integrity: A loose or failed locking nut on an aerial lift can allow panels, guards, or structural connections to shift — replacing worn hardware with the correct OEM nut maintains the secure assemblies the machine depends on.
A Nylock nut, also called a nylon-insert lock nut, is a standard hex nut with a nylon collar bonded into the top of the nut. As the nut is threaded onto a bolt or stud, the nylon deforms slightly around the thread, creating friction that resists rotation from vibration and dynamic loading. This locking action keeps fastened connections secure without the need for thread-locking adhesives or secondary hardware. When the nylon insert is worn, cracked, or the nut has been removed and reinstalled repeatedly, the locking force diminishes and the connection can work loose during machine operation — making timely replacement with a correctly specified nut an important part of routine hardware maintenance.
