Key Features
- Torque Lock Flange Design — The integrated flange distributes clamping load evenly across the joint face, while the torque-lock feature resists loosening under vibration and dynamic load cycles common in aerial and telehandler operation.
- Broad Genie Equipment Compatibility — Fits Genie SX and S series telescopic booms, Z and ZX articulating booms, and GTH telehandlers, covering a wide range of Genie equipment in a single part number.
- Direct Installation — Same thread form and nut geometry as the original component means no chasing threads or reworking the mating fastener to achieve correct engagement.
A flange nut combines a standard nut with an integrated washer-like flange at its base. The flange spreads clamping force across a wider surface area than a plain nut, reducing the risk of joint surfaces deforming under load. The torque-lock feature — typically a prevailing-torque element built into the nut — resists self-loosening caused by vibration, shock loads, and repeated machine cycles. A nut that has backed off or failed can allow structural connections to shift or separate, so replacing a worn or damaged fastener with the correct OEM part is straightforward preventive maintenance that keeps the joint secure.
