The Genie 1256456GT is a genuine OEM TL Nut, M8-1.25, DIN980, 10, ZAB built for a wide range of Genie equipment, including GTH telehandlers, Z-series articulating boom lifts, and RL4 light towers. As a factory-original fastener, it meets the dimensional and material standards Genie specifies for this application. Confirm part number 1256456GT against your machine's parts manual to ensure it is the correct item for your unit before ordering.
Key Features
- Genuine OEM Specification — Manufactured to Genie's exact material grade and dimensional tolerances for the M8-1.25 thread form, DIN980 standard, Grade 10, ZAB finish.
- Exact-Thread Replacement — M8-1.25 thread pitch and DIN980 all-metal prevailing-torque profile install directly in place of the original fastener without rework.
- Broad Equipment Compatibility — Fits Genie GTH telehandlers, Z-series articulating booms (including DC and FE Hybrid variants), and RL4 vertical mast light towers.
- Prevailing-Torque Retention — The DIN980 all-metal locking design resists loosening under vibration and dynamic loads, maintaining joint integrity over the service life of the fastener.
- Corrosion-Resistant Finish — ZAB zinc-alloy finish provides surface protection suited to the demanding outdoor and jobsite environments these machines operate in.
A prevailing-torque nut relies on a deformed or all-metal locking feature built into the nut itself to resist rotation without a separate locking element. On equipment subject to continuous vibration and cyclic loading — such as boom lifts, telehandlers, and light towers — fasteners that allow joint loosening can lead to misalignment, accelerated wear on adjacent components, or loss of structural integrity at the connection point. Replacing a worn or missing nut with the correct OEM-specified part, sized and graded to match the original, restores the clamping load the joint was designed to carry and keeps the connection secure through normal service conditions.
