The Genie 1255800GT is a genuine OEM Hex Head Flange Screw, 5/16-18x1.75, 8, ZAG designed for the Genie S-45 XC telescopic boom lift and Genie GTH series telehandlers, including the GTH-636, GTH-844, GTH-1056, and GTH-1256. As a factory-supplied fastener, this screw is manufactured to the same dimensional and material standards as the original hardware, ensuring a correct fit without rework or modification. Cross-reference part number 1255800GT against your machine's parts manual to confirm it is the right fastener for your application before ordering.
Key Features
- OEM Grade Hardware — Manufactured to Genie's dimensional and grade specifications, this Class 8 hex head flange screw delivers the clamping force and thread engagement the original design requires.
- Integrated Flange Design — The built-in flange distributes load across a wider bearing surface, reducing the need for a separate washer and simplifying reassembly.
- Direct OEM Replacement — Threads, head geometry, and length match the original fastener, so this screw reinstalls into existing hardware locations without any adjustment.
- Broad Genie Fitment — Fits the S-45 XC telescopic boom and GTH-series telehandlers, making it a practical stocking fastener for mixed Genie fleets.
A hex head flange screw combines a standard hex head with an integral washer-like flange beneath it, spreading clamping load over a larger surface area than a plain hex head alone. This reduces the risk of joint loosening and surface damage on the mating component. When a fastener of this type is missing, stripped, or corroded, the joint it secures can work loose under vibration and load cycles — potentially allowing panels, brackets, or structural members to shift. Replacing a worn or damaged screw with the correct OEM part restores the specified clamping integrity to that connection.
