Key Features
- Genuine OEM Fastener — Manufactured to Genie's exact thread pitch and flange dimensions, ensuring dimensional conformity and consistent clamp load on every installation.
- Torque Lock Flange Design — The integrated flange distributes load across a wider bearing surface, while the torque-locking feature resists loosening under vibration.
- Direct OEM Replacement — Sized at 8-32 female threading to match the original specification, so this nut installs without modification or fitting adjustments.
- Broad Genie Compatibility — Fits Genie S-series telescopic booms, Z-series and ZX-series articulating booms, and GTH telehandlers, making it a practical fastener to keep on hand for mixed Genie fleets.
A flange nut combines a standard nut with an integrated washer-like flange at its base, spreading the clamping force over a larger surface area than a conventional nut. This reduces the risk of the fastener pulling through or distorting softer mounting surfaces. The torque-locking feature — typically a nylon insert, deformed thread, or similar locking element — creates friction that resists self-loosening caused by machine vibration during normal operation. A worn or missing nut of this type can allow fastened joints to work loose over time, leading to play, misalignment, or component separation. Replacing a failed fastener with the correct OEM part ensures the joint performs as originally engineered.
