Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's original M8 specification, with correct inner diameter, outer diameter, and bite angle to provide consistent locking force under torque.
- Direct Hardware Match — Replaces the original lock washer without modification, seating correctly against M8 fasteners and mating surfaces as installed at the factory.
- Broad Equipment Coverage — Fits Genie GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, TZ and TMZ trailer-mounted booms, GTH telehandlers, and TML light towers across a wide range of model years.
- Fastener Integrity — A sound lock washer prevents fastener back-out under vibration and dynamic loading. A missing or deformed washer allows bolted connections to loosen over time, which can compromise structural and mechanical joints on the machine.
A lock washer is a thin hardened ring with a split or shaped profile designed to resist loosening of a threaded fastener under vibration and cyclic loads. When a bolt or nut is torqued down, the washer's edges bite into both the fastener face and the mating surface, creating resistance against rotational back-out. On mobile equipment that experiences constant movement and vibration, a failed or absent lock washer allows joints to work loose gradually — which can lead to misalignment, noise, or component failure at the connection point. Replacing a worn or damaged lock washer with the correct OEM part restores the holding integrity of the joint.
