Key Features
- Genuine OEM Dimensions — Manufactured to the exact .688 X 1.160 X .09 specification called out in Genie parts documentation, ensuring correct load distribution and seating.
- ZAG Finish for Corrosion Resistance — The zinc-alloy galvanized coating helps the washer stand up to outdoor and rough-terrain environments common on Genie boom and scissor applications.
- Direct Drop-In Replacement — Matches the original hardware profile so it seats correctly against mating fasteners and structural surfaces without rework or shimming.
- Broad Fitment Across Two Machine Families — Fits Genie GS scissor lifts (GS-3384 through GS-5390) and Z-series articulating booms (Z-30/20 N and Z-34/22 variants), making it a versatile stocking part for mixed fleets.
- Structural Integrity Where It Counts — On aerial lifts, fastener hardware plays a direct role in keeping structural connections secure at height; using the correctly rated OEM washer supports the integrity of those assemblies.
A flat washer serves as a load-spreading interface between a fastener — typically a bolt or nut — and the surface it clamps. By distributing clamping force over a wider area, it prevents the fastener from pulling through or damaging softer or thinner material, and it helps maintain consistent clamping pressure over time. On Genie scissor lifts and articulating booms, washers like this one appear throughout structural pivot points, hydraulic component mounts, and frame assemblies. When a washer is deformed, corroded, or sized incorrectly, it can allow fasteners to loosen under vibration and cyclic loading — compromising the integrity of the joint and the safety of the connection.
