The Genie 1256312GT is a genuine OEM Lock Washer, #10 designed for a wide range of Genie aerial work platforms and telehandlers, including S series telescopic boom lifts, Z series articulating boom lifts, GS series scissor lifts, and GTH telehandlers. As a direct OEM replacement, this lock washer is manufactured to the same specification as the original hardware installed at the factory, ensuring correct torque retention and a secure connection wherever it is used in the assembly. Cross-reference part number 1256312GT against your parts manual to confirm fitment for your specific machine configuration before ordering. From compact electric scissors like the GS-1530 to heavy-duty booms like the S-85 XC and articulating models like the Z-45/25J Bi-Energy, this lock washer covers an exceptionally broad range of Genie equipment.
Key Features
- Genuine OEM Zinc-Coated Hardware — The ZAG (zinc-plated) finish provides corrosion resistance suited to the outdoor and mixed-environment conditions these machines operate in, maintaining the hardware's integrity over repeated service cycles.
- Direct-Fit Fastener — Sized and toleranced to the original #10 specification, this washer seats and torques correctly in the same positions as the factory-installed hardware, with no rework or modification to surrounding components.
- Broad Genie Equipment Compatibility — Fits Genie S and Z series boom lifts, GS series scissor lifts, and GTH series telehandlers, making it a practical stock item for fleets running multiple Genie machine types.
- Maintains Fastener Clamping Force — Lock washers resist loosening caused by vibration and dynamic loading. A worn or missing lock washer allows fasteners to back out over time, leading to mechanical play and potential component failure in critical joints.
- Operational Safety at Every Fastened Joint — On aerial lift equipment, loose fasteners in structural, hydraulic, or control-system connections are a direct safety concern. Using the correct OEM-spec lock washer at every service point keeps joints secure and the machine performing as intended.
A lock washer is a hardened ring installed beneath a fastener to prevent it from backing out under vibration and cyclical loading. On mobile aerial equipment and telehandlers, mechanical vibration during travel and operation is constant, and any fastener without adequate locking hardware can gradually loosen, allowing joints to shift or separate. The #10 Lock Washer, #10 (1256312GT) provides the spring tension and bite needed to keep threaded connections tight between scheduled maintenance intervals, protecting both the structural integrity of the assembly and the safety of the operator. When this component is missing or damaged, fasteners in the affected joint become vulnerable to self-loosening, which can progress undetected until a more significant mechanical issue develops.
