Key Features
- Exact Thread and Length Match — 5/8-11 thread pitch and 4.50-inch grip length match the original factory fastener, ensuring correct engagement without modification.
- Plain Finish — Uncoated finish matches the original specification, maintaining dimensional accuracy at the fastener head and mating surface.
- Genuine OEM Part — Sourced directly from Genie, this fastener meets the same dimensional and material tolerances as the part it replaces on the Z-34/22 IC.
- Confirmed Fitment — Designed specifically for the Genie Z-34/22 IC articulating boom lift, giving you confidence you are installing the correct part.
A hex head cap screw is a structural fastener that clamps two or more components together under a specified torque load, preventing movement, vibration-induced loosening, or separation during machine operation. On aerial work platforms, fasteners like this one are used at critical connection points throughout the structure, drive, and platform systems. Using the correct grade and length — in this case a Grade 8 fastener at 4.50 inches — is essential, as substituting an incorrect grade or length can result in fastener failure, joint movement, or component damage over time.
