The Genie 1256113GT is a genuine OEM Lock Washer, 3/4 ZAG designed for Genie GTH-series telehandlers, including the GTH-636, GTH-1056, and GTH-1256. As a direct OEM replacement, this lock washer is built to the exact specification Genie requires, ensuring proper clamping load and fastener retention in the demanding environments these telehandlers operate in. Cross-reference part number 1256113GT against your parts manual to confirm fitment before ordering. Sourced directly through authorized channels, this component delivers the fit and function your machine was engineered around.
Key Features
- Genuine OEM Zinc-Alloy Construction — The ZAG (zinc-alloy galvanized) finish provides corrosion resistance suited to outdoor telehandler applications, maintaining fastener integrity in wet or high-wear environments.
- Correct 3/4 Sizing for Direct Installation — Sized to match the 3/4-inch fastener specifications used in Genie GTH telehandler assemblies, this washer seats and torques correctly without shimming or modification.
- Fits GTH-Series Telehandlers — Compatible with the GTH-636, GTH-1056, and GTH-1256, covering a broad range of Genie telescopic handler configurations used across construction and industrial worksites.
- Prevents Fastener Back-Out Under Load — Lock washers are critical for maintaining clamp force on bolted joints subject to vibration. A worn or missing washer allows fasteners to loosen over time, leading to joint failure and structural instability.
- Structural Joint Integrity Matters on Aerial Equipment — On telehandlers, fastener retention in boom, carriage, and frame joints directly affects safe load handling. Using the correct OEM-spec washer supports the mechanical integrity those joints depend on.
A lock washer works by biting into the mating surfaces of a bolted joint, creating resistance that prevents the nut or bolt from rotating loose under vibration or dynamic loading. In a telehandler like the GTH-series, where the boom, outriggers, and carriage assemblies experience repeated stress cycles during lifting and traveling, maintaining clamp load across every bolted connection is essential. When a lock washer fails or is omitted, fasteners can back out gradually, causing joint slippage, misalignment, or structural failure that may not be immediately visible until damage is already done.
