The Genie 21166GT is a genuine OEM Wheel Hub Lug Bolt, 5/8-18 built for Genie S series telescopic boom lifts and Z series articulating boom lifts. As a genuine OEM part, it is manufactured to the same dimensional and material standards as the original hardware, ensuring a correct, secure fit at the wheel hub. This lug bolt is confirmed to fit a wide range of Genie boom lift models, including the S-60, Z-34/22 N, Z-34/22 Bi-Energy, Z-33 DC Power, Z-60/34, Z-45/22, and Z-30/20 N, among others. Cross-reference part number 21166GT against your machine's parts manual to confirm it is the correct item for your specific unit before ordering.
Key Features
- Genuine OEM Specification — Manufactured to Genie's original dimensional and thread standards, so the 5/8-18 thread engages correctly without risk of cross-threading or improper torque loading.
- Exact Wheel Hub Fit — Designed as a direct replacement for the original lug bolt position, fitting the wheel hub mounting pattern without modification.
- Broad Boom Lift Compatibility — Fits Genie S series telescopic booms and a wide range of Z series articulating booms, including Bi-Energy, IC, DC Power, N, and MP variants.
- Structural Fastening Integrity — A correctly torqued lug bolt keeps the wheel firmly seated at the hub. A loose, damaged, or incorrect bolt compromises wheel retention and puts the machine and operator at risk.
A lug bolt threads through the wheel and into the wheel hub to clamp the wheel securely against the hub flange. When correctly installed and torqued, lug bolts distribute clamping load evenly across the wheel mounting surface, keeping the wheel fixed during travel and lift operations. A stripped thread, incorrect thread pitch, or failed lug bolt allows wheel movement that can lead to vibration, stud damage, or wheel separation — conditions that are especially hazardous on self-propelled aerial lift equipment operating on uneven terrain.
