The Genie 1256456GT is a genuine OEM TL Nylock Nut, M8-1.25, DIN980, 10, ZAB built for a range of Genie equipment including RL4 light towers, GTH telehandlers, and Z-series articulating booms. As a direct OEM replacement, this nut matches the original specification for thread pitch, grade, and finish — so it installs exactly where the original did without alteration. Cross-reference part number 1256456GT against your machine's parts manual to confirm it is the correct fastener for your unit before ordering.
Key Features
- M8-1.25 Thread Conformity — The M8-1.25 thread pitch ensures correct engagement with mating components, eliminating the risk of cross-threading or loose retention that an incorrect fastener would introduce.
- Nylon-Insert Locking — The prevailing-torque locking element resists loosening under vibration and dynamic loads common in aerial and telehandler applications, maintaining clamp load over the service life of the machine.
- Broad Genie Fitment — Fits RL4 vertical mast light towers, GTH-636, GTH-844, GTH-1056, and GTH-1256 telehandlers, Z-60/37 DC and Z-60 DC articulating booms, and the Z-45 DC — verified genuine OEM coverage across multiple Genie equipment families.
- Genuine OEM Sourcing — Supplied as an authentic Genie OEM part through DHS Equipment, ensuring the fastener you receive is the same item specified in the Genie parts manual.
A Nylock nut uses a nylon insert at the top of the nut to grip the bolt thread and resist rotation under vibration, maintaining the clamping force holding two components together. On mobile equipment such as aerial lifts and telehandlers, fasteners are subjected to constant vibration and dynamic loading — a nut that works loose can allow structural or mechanical joints to shift, leading to accelerated wear or component failure. Replacing a worn or lost fastener with the correct OEM-specified nut restores the designed clamping integrity to that joint and keeps the assembly operating as intended.
