The Genie 1255800GT Hex Head Flange Screw, 5/16-18 x 1.75 is a genuine OEM fastener built for a wide range of Genie telescopic boom lifts, scissor lifts, telehandlers, and articulating booms. Sourced directly through Genie's OEM supply chain, this screw is manufactured to the exact grade, thread pitch, and finish specified for the original equipment. It fits Genie S and Z series boom lifts, GS series scissor lifts, and GTH series telehandlers, covering a broad cross-section of the Genie lineup. Cross-reference part number 1255800GT against your machine's parts manual to confirm it is the correct fastener for your specific unit and application.
Key Features
- OEM Grade and Finish — Manufactured to Grade 8 specification with a zinc-alloy (ZAG) coating that meets the corrosion-resistance standard called out in the original Genie parts manual for this fastener.
- Correct Thread and Dimensional Spec — 5/16-18 UNC thread and 1.75-inch length match the exact dimensions of the original screw, so this part installs cleanly without rework or modification to the mating hardware.
- Broad Genie Equipment Compatibility — Fits Genie S series telescopic booms (including XC, TRAX, and HF variants), GS series scissor lifts, GTH series telehandlers, and Z series articulating booms, making it a practical stocking item for mixed Genie fleets.
- Integral Flange Bearing Surface — The flanged head distributes clamping load over a wider area than a standard hex head screw, reducing the risk of surface damage or fastener loosening under vibration and load cycles common to aerial lift and telehandler operation.
- Genuine OEM Traceability — As a genuine Genie part, this screw carries full OEM traceability, so you know it meets the material and performance standards set for the original build — not an approximation of it.
A hex head flange screw combines a standard hex-drive head with an integrated washer-like flange beneath it, eliminating the need for a separate flat washer and providing a consistent, load-spreading bearing surface. In mobile equipment like aerial lifts and telehandlers, fasteners work under repeated vibration, structural loads, and environmental exposure — conditions that can cause underspecified screws to loosen, strip, or corrode prematurely. Using the correct OEM-spec screw with the right grade, thread form, and protective finish ensures the joint holds its intended clamp load over the service life of the machine. When a fastener is damaged or missing, replacing it with the exact specified part maintains the integrity of the assembly it secures.
