Sourced directly from Genie, this fastener matches the exact thread specification and locking configuration called out in the original parts manual. Cross-reference part number 45303GT against your machine's parts documentation to confirm it is the correct item for your application before ordering.
Key Features
- Genuine OEM Thread Conformity — Manufactured to the exact 1.125-12 thread specification, ensuring the nut seats and torques correctly without rework or adaptation.
- Nylon Insert Locking — The nylock collar resists loosening under vibration, maintaining clamp load over the demanding duty cycles typical of articulating boom lifts.
- Direct OEM Replacement — Identical in dimension and material to the factory-installed fastener, so it fits and functions exactly as the original.
- Broad Z-Series Compatibility — Fits Genie Z-60/34, Z-45/22 MP, and Z-45/22 articulating booms, making it a practical stocking item for fleets running multiple Z-series models.
- Structural Fastener Integrity — A fastener that has lost its locking ability can back off under load, compromising the joint it secures. Replacing a worn nut with the correct OEM part restores the connection to its designed holding strength.
A Nylock nut uses a nylon insert at the top of the nut to grip the bolt threads and resist rotation caused by vibration or dynamic loading. Unlike a standard hex nut, the nylon collar deforms around the thread form when driven, creating friction that holds the nut in position without an additional locking washer or adhesive. On articulating boom lifts, fasteners are subject to continuous movement and vibration during operation, and a nut that has worked loose or whose locking insert has degraded can allow joint movement that leads to premature wear or structural compromise. Replacing a spent Nylock nut with the correct OEM part restores the joint to its original specification.
