The Genie 1263142GT is a genuine OEM Hex Head Cap Screw, 5/8-11x4.5, Grade 8, Zinc built for Genie S series telescopic boom lifts, Z series articulating boom lifts, and TZ series trailer-mounted articulating booms. As a factory-supplied fastener, this screw meets the exact dimensional and material specifications Genie engineers required at the point of assembly. Confirmed fitment includes the S-45 XC, Z-45/25 IC, Z-45 XC, Z-51/30J, Z-34/22 N, Z-34/22 IC, Z-34 IC, TZ-34/20, and TZ-50/30.
Key Features
- Exact OEM Thread Specification — The 5/8-11x4.5 thread and length match the original Genie engineering spec, so this screw seats correctly without rework or shimming.
- Broad Boom Lift Fitment — Fits a wide range of Genie S series telescopic and Z series articulating boom lifts, including trailer-mounted TZ models, making it a versatile stock item for mixed fleets.
- Structural Integrity — A correctly torqued, properly specified fastener maintains the clamping load that keeps structural joints and critical assemblies secure during boom operation.
A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head, driven by a wrench to develop and hold a precise clamping load between joined components. On aerial boom lifts, fasteners like this one are used throughout structural joints, pivot assemblies, and mounting points where maintaining correct torque is essential to safe and stable boom movement. A fastener that is the wrong grade, wrong thread pitch, or wrong length cannot develop the required clamping force and may loosen under load or vibration — making part number verification against your machine's parts manual the right first step before ordering.
