The Genie 1256856GT is a genuine OEM Hex Head Flange Screw, 3/8-16 x 2.5, 8, ZAG built for a broad 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 matches the original specification for thread pitch, grade, and finish, ensuring a correct fit with no guesswork. Cross-reference part number 1256856GT against your machine's parts manual to confirm it is the right fastener for your application before ordering.
Key Features
- Flanged Head Design — The integrated flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer and maintaining consistent joint integrity.
- Exact Thread Specification — Cut to 3/8-16 x 2.5 dimensions, this fastener threads directly into its intended bore without modification, preserving the holding strength the original design calls for.
- Wide Equipment Compatibility — Fits Genie GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, and GTH telehandlers, making it a practical stocking fastener for mixed Genie fleets.
- Structural Integrity — A correctly specified, properly torqued screw keeps panels, guards, and structural members secured. A stripped, corroded, or under-grade fastener can allow movement or allow a component to shift under load.
A hex head flange screw combines the function of a standard hex bolt and a built-in washer into one fastener. The flanged bearing surface spreads the clamping force across a larger area than a plain bolt head, helping to prevent joint relaxation in applications subject to vibration — common on mobile aerial equipment. When a fastener of this type is missing, corroded, or replaced with an incorrect grade, the joint it secures can loosen over time, potentially compromising the component it holds in place. Using the correct OEM-spec part number 1256856GT ensures the thread engagement, grade strength, and corrosion protection all match what Genie engineers specified for that location on the machine.
