Key Features
- Exact Thread and Dimensional Match — The 5/16-18 thread pitch and 1.75-inch length are specified to match the original fastener exactly, seating correctly in the host assembly without modification.
- Genuine OEM Sourcing — Supplied directly through the Genie OEM parts chain, this screw carries the same part number and specification as the fastener installed at the factory.
- Broad Fitment Across Genie Families — Compatible with the S-65 XC telescopic boom, Z-62/40 articulating boom, GTH-1056 telehandler, and select additional Genie equipment.
- Structural Integrity You Can Count On — A fastener at the correct grade and spec keeps assembled components secure under load and vibration; an underspec or mismatched screw risks joint failure and component damage.
A hex head cap screw is a threaded fastener used to clamp or secure components within a mechanical assembly. The hex head allows high torque to be applied with standard hand or power tools, while the grade rating and thread form determine how much clamping force the fastener can safely sustain. Using the correct grade, thread, length, and finish ensures the joint holds to specification — an undergrade or incorrect-length fastener can work loose, strip threads, or fail to develop the clamping load the assembly requires, leading to component movement, wear, or damage over time.
