Key Features
- Zinc-Coated for Corrosion Resistance — The ZAG (zinc) finish provides a protective barrier against rust and oxidation, extending service life in outdoor and demanding jobsite environments.
- Genuine OEM Hardware — Sourced directly from Genie, this lock washer meets the exact material hardness and dimensional spec of the original fastener assembly, ensuring consistent clamping force.
- Drop-In Installation — Sized at 1/4 inch to match the original fastener stack, this washer installs directly without modification to existing hardware or mounting points.
- Wide Fleet Coverage — Fits Genie S and SX telescopic booms, Z and ZX articulating booms, GS scissor lifts, GTH telehandlers, and TZ trailer-mounted booms, making it a practical stock item for mixed fleets.
- Prevents Fastener Loosening Under Vibration — Lock washers are critical in high-vibration environments; a worn or missing washer allows bolts to back out, compromising the integrity of structural and mechanical connections.
- Structural Connection Integrity — On aerial lift platforms and boom assemblies, properly secured fasteners are essential to safe machine operation — using the correct OEM-spec hardware maintains the integrity of every joint it secures.
A lock washer is a small but essential component in any bolted joint subjected to vibration, load cycling, or movement. It sits between the fastener and the mating surface, using its spring tension or toothed profile to resist rotation and prevent the bolt or nut from loosening over time. On aerial lifts and telehandlers — machines that experience constant dynamic loads, platform movement, and drivetrain vibration — even a single loose fastener in a critical joint can lead to premature wear, misalignment, or structural compromise. Replacing a worn or missing lock washer with the correct OEM-spec part restores the clamping integrity of the connection and helps ensure the fastener stays properly torqued throughout its service life.
