Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's exact thread pitch, shank length, and finish specifications, ensuring the fastener seats and torques correctly in its intended location.
- Direct OEM Replacement — Matches the original fastener in thread size (1-8) and length (12.5), so it installs without modification using standard tooling.
- Broad Boom Lift Fitment — Fits Genie S-series telescopic and Z/ZX-series articulating boom lifts, including the S-60 HC, ZX-135/70, and Z-80/60.
- Structural Integrity — A correctly specified fastener at this size maintains the clamping force and joint integrity the assembly depends on; an incorrect or worn fastener can allow movement or loosening in critical joints.
A hex head cap screw is a high-strength threaded fastener used to clamp structural components together with a controlled torque load. At the 1-8 thread pitch and 12.5-inch length specified here, this screw is designed for heavy-duty structural joints on large boom lift assemblies. When a fastener of this type is missing, under-torqued, or replaced with an incorrect grade or size, the joint it secures may shift or loosen under load — compromising the integrity of the structure it holds. Using the correct OEM part ensures the thread engagement, clamp load, and finish all meet the requirements of the original design.
