The Genie 1259896GT Hex Head Flange Screw is a genuine OEM fastener built for Genie S-series telescopic boom lifts and GTH telehandlers. Sourced directly through the Genie OEM supply chain, this screw is manufactured to the same dimensional and material standards as the hardware originally installed on the machine. It fits S-40, S-45, S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, and S-45 HF telescopic booms, as well as GTH-1044, GTH-1056, GTH-1244, GTH-1256, and GTH-1544 telehandlers — cross-reference part number 1259896GT against your machine's parts manual to confirm the correct application before ordering.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to the same thread pitch, grip length, and flange diameter as the original hardware, ensuring correct torque transfer and seating when installed.
- Direct Hardware Replacement — This screw installs in place of the original without reworking mating holes or hardware, maintaining the designed clamping load for the joint.
- Broad Genie Equipment Compatibility — Fits multiple S-40 and S-45 telescopic boom variants — including XC, TRAX, and HF models — as well as a range of GTH telehandler configurations.
- Grade 8 Strength Rating — The grade 8 specification delivers the tensile and shear strength required for structural and mechanical fastening applications on heavy equipment.
- Zinc Alloy-Galvanized (ZAG) Finish — The ZAG coating provides corrosion resistance suited to the outdoor and variable-weather environments in which these machines regularly operate.
A hex head flange screw combines a standard hex head with an integrated flange that acts as a built-in washer, distributing clamping load across a wider bearing surface and reducing the risk of fastener pull-through or surface damage. On equipment like telescopic booms and telehandlers, where structural joints are subjected to vibration and repeated load cycles, using the correctly specified fastener — right thread, right grade, right finish — is essential to maintaining joint integrity. A screw of the wrong grade or dimensions can work loose or fail under load, compromising the connection it secures.
