The Genie 49407GT is a genuine OEM Lock Washer, M6 designed for a wide range of Genie aerial lifts, telehandlers, and light towers. As a factory-sourced component, this washer is manufactured to the same specification as the hardware originally installed on the machine, ensuring a correct and consistent fit across every supported model. This part is confirmed for use on Genie S and SX telescopic booms, Z and ZX articulating booms, GS scissor lifts, GTH telehandlers, TZ and TMZ trailer-mounted booms, and TML light towers. Cross-reference part number 49407GT against your Genie parts manual to confirm the correct application before ordering.
Key Features
- Genuine OEM Hardware Grade — Sourced directly from Genie, this lock washer meets the exact material and dimensional specification used in original assembly, delivering the consistent clamping load the fastener joint requires.
- M6 Thread Compatibility — Sized for M6 fasteners, this washer seats and bites correctly without shimming or adaptation, maintaining proper torque retention on M6 bolt connections throughout the machine.
- Broad Fleet Coverage — Fits Genie S and Z series boom lifts, GS scissor lifts, GTH telehandlers, TZ and TMZ trailer-mounted booms, and TML light towers, making it a practical stock item for mixed Genie fleets.
- Prevents Fastener Loosening — The hardened lock profile bites into mating surfaces under vibration and load cycling, resisting the bolt back-off that can compromise structural connections on mobile equipment.
- Critical Fastener Integrity — On aerial lifts and elevated work platforms, maintaining correct bolt preload is directly tied to structural and mechanical safety; using the correct OEM lock washer supports the integrity of those connections.
A lock washer is a hardened, split or toothed ring placed beneath a bolt or nut to resist loosening caused by vibration, dynamic loads, and repeated movement cycles. As equipment operates — traveling over uneven ground, extending and retracting booms, or enduring engine and hydraulic vibration — fasteners are continuously subjected to forces that can cause gradual back-off. The lock washer's deformed profile creates a spring tension and a biting edge that maintains clamping force between the fastener and the mating surface. When a lock washer is worn flat, cracked, or missing entirely, the bolt it secures can work loose over time, leading to loosened structural joints, fluid-carrying connections, or electrical grounds — any of which can affect machine performance or safety.
