The Genie 1256856GT Hex Head Flange Screw, 3/8-16 x 2.5 is a genuine OEM fastener built for a wide range of Genie equipment, including GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, and GTH telehandlers. As a direct OEM replacement, this screw is manufactured to the same dimensional and material standards as the original hardware installed at the factory. Cross-reference part number 1256856GT against your machine's parts manual to confirm it is the correct item for your specific unit and serial range. Keeping the correct fastener on hand means you can complete hardware replacements without delays when the need arises.
Key Features
- OEM-Grade Fastener Material — Zinc-coated alloy construction with a Grade 8 rating delivers the clamp load and corrosion resistance the original design calls for.
- Integrated Flange Design — The built-in flange distributes clamping load across a wider bearing surface, eliminating the need for a separate washer and speeding up installation.
- Broad Genie Fleet Coverage — A single part number covers GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, and GTH telehandlers, making it a practical stocking item for mixed Genie fleets.
- Correct Thread Specification — The 3/8-16 x 2.5 thread and length are matched to Genie's engineering requirements, so the screw seats and torques correctly without rework.
- Structural Integrity Where It Counts — A fastener that is incorrect in grade, thread pitch, or length can work loose or fail under load. Using the right OEM hardware maintains the joint integrity the machine was designed around.
A hex head flange screw combines the function of a standard hex head cap screw with an integral flanged washer beneath the head. The flange spreads the clamping force over a larger surface area, reducing the risk of the fastener pulling through or deforming the mating material. On Genie aerial lifts and telehandlers, structural and mechanical joints rely on fasteners torqued to precise specifications — a fastener that is the wrong grade, thread pitch, or length compromises joint integrity and can lead to loosening or failure over time. Replacing worn or damaged hardware with the correct OEM part restores the joint to its original specification and supports safe, dependable machine operation.
