The Genie 123663GT is a genuine OEM Hex Head Cap Screw, 1/2-13 x 1.25, GR8 designed for Genie S-series telescopic boom lifts, Z-series articulating boom lifts, and GTH telehandlers. As a genuine OEM part, this screw is produced to the same specifications as the hardware installed at the factory, ensuring a consistent, secure fit across all listed applications. Compatible models include the S-60, S-60 XC, S-60 TRAX, S-65, S-65 TRAX, S-60 HC, S-60X, Z-40/23N, Z-40/23N RJ, GTH-636, GTH-644, GTH-842, GTH-844, GTH-1048, and GTH-1056. Cross-reference part number 123663GT against your machine's parts manual before ordering to confirm it is the correct item for your unit.
Key Features
- Grade 8 Strength Rating — GR8 construction delivers the high tensile strength required for structural and load-bearing fastener positions on Genie booms and telehandlers.
- Genuine OEM Specification — Manufactured to Genie OEM dimensional standards with a 1/2-13 thread pitch and 1.25-inch length, so this screw seats and torques correctly without modification.
- Broad Genie Fleet Compatibility — Fits S-series telescopic booms, Z-series articulating booms, and GTH telehandlers, making it a practical stocking item for mixed Genie fleets.
- Corrosion-Resistant Finish — The "Y" designation indicates a yellow zinc or equivalent protective finish, providing corrosion resistance suited to outdoor and rough-terrain operating environments.
- Structural Integrity Where It Counts — A properly torqued, correctly graded fastener maintains tight joints at critical connection points; a worn, stripped, or incorrect-grade screw can allow movement and accelerate component wear.
A hex head cap screw is a fully threaded or partially threaded fastener tightened with a wrench, used to clamp or join structural components at a defined torque. In aerial lift and telehandler applications, fasteners at this size and grade are commonly found at structural pivot points, boom section joints, and equipment mounting positions where consistent clamp load is essential. When a fastener of the wrong grade or incorrect thread spec is substituted, joint integrity can degrade over time — making it important to replace hardware with the correct OEM-specified part. Confirm part number 123663GT against your machine's parts manual to ensure this is the right screw for your specific application.
