As a direct OEM part, it meets the dimensional and material standards Genie specifies for this application, ensuring a correct fit without modification. Cross-reference part number 1259896GT against your machine's parts manual to confirm it is the right fastener for your specific assembly point before ordering.
Key Features
- Exact Thread and Dimensional Spec — 5/8-11 thread pitch and 2.5-inch length match the Genie-specified fastener geometry, seating flush and threading fully without rework.
- Integrated Flange Design — The hex head flange distributes clamping load across a wider bearing surface, reducing the risk of joint loosening under operational vibration.
- Broad Genie Fitment — Fits the S-45 XC telescopic boom lift and GTH-1056 and GTH-1256 telehandlers, covering a range of Genie equipment families.
- Genuine OEM Part — Supplied directly by Genie, this fastener is the same component used in original assembly, not an approximation of it.
A hex head flange screw combines a standard hex head with a built-in flanged washer at its base, creating a wider load-bearing surface without the need for a separate washer. This design keeps the joint more secure under vibration and cyclical loading — conditions common in aerial lifts and telehandlers during daily operation. When a fastener stretches, corrodes, or strips, the clamped joint can shift or loosen, affecting structural integrity at that connection point; replacing it with the correct-spec OEM screw restores the joint to its designed clamping force.
