The Genie 1255764GT is a genuine OEM Lock Washer, 5/16 ZAG designed for a wide range of Genie scissor lifts, telehandlers, and boom lifts. As a direct OEM replacement, this washer meets the same specifications as the original hardware installed at the factory, making it the straightforward choice when servicing or rebuilding fastener assemblies across compatible machines. This component fits Genie GS scissor lifts, GTH telehandlers, the Z-80/60 articulating boom, and the RL4 vertical mast lift — cross-reference part number 1255764GT against your parts manual to confirm fitment for your specific unit.
Key Features
- Genuine OEM Hardware Grade — Produced to Genie's own material and dimensional specification for a zinc-alloy galvanized (ZAG) finish, giving this washer the corrosion resistance and hardness needed in outdoor and heavy-use environments.
- Correct Thread-Series Match — Sized at 5/16 to seat precisely against mating fasteners in the original assembly, eliminating the guesswork that comes with sourcing generic hardware.
- Broad Fleet Compatibility — Fits Genie GS scissor lifts, GTH telehandlers, the Z-80/60 articulating boom, and the RL4 vertical mast lift, making this a useful stock item for mixed Genie fleets.
- Maintains Fastener Clamp Load — A lock washer that is worn, flattened, or missing allows bolts to back out under vibration. Replacing it with this part restores proper tension retention throughout the joint.
- Direct Drop-In Installation — This part installs in place of the original with no modification to surrounding hardware, keeping service time short during scheduled maintenance or field repairs.
A lock washer sits between a bolt head or nut and the mating surface to resist loosening caused by vibration and dynamic loads. The split or toothed profile bites into both surfaces, maintaining clamp force across the joint even as the machine cycles through repeated movement and stress. On aerial lifts and telehandlers — where structural and mechanical fasteners are subject to constant vibration from travel, extension, and loading — a compromised or missing lock washer can allow critical bolts to work loose over time. Replacing worn or damaged washers during routine service helps keep fastener joints secure and structurally sound.
