Key Features
- Exact Thread and Length Specification — 3/8-16 thread pitch and 4.5-inch length match the OEM specification exactly, ensuring proper torque and seating without modification.
- Genuine OEM Quality — Sourced directly from Genie, this screw meets the dimensional and material standards set for the original assembly, with no guesswork on grade or coating.
- Broad Genie Fitment — Compatible with GTH-1056, GTH-1256, TZ-34/20, TZ-50/30, and Z-62/40 machines, covering both telehandler and boom lift applications in a single part number.
A hex head cap screw is a fully threaded or partially threaded fastener used to clamp, secure, or join structural components within a machine. The combination of thread grade, length, and surface finish is critical — an undersized or lower-grade fastener in a high-load joint can back out, deform, or fail under the dynamic stresses generated during boom extension, load handling, or travel. Replacing a worn or damaged screw with the correct OEM specification part restores the joint to its designed clamping load and helps maintain structural integrity across the assembly.
