Key Features
- Exact OEM Dimensions — Manufactured to the specified .688 x 1.160 x .09 profile, delivering the precise bearing surface and load distribution the fastener assembly requires.
- Genuine Genie OEM Part — Produced to Genie's own material and hardness standards, so the washer performs consistently under the clamping loads found in boom-lift structural and mechanical joints.
- Broad Boom-Lift Fitment — Compatible with S-40 and S-45 telescopic booms and the Z-34/22 N, Z-34/22 DC, Z-34/22 Bi-Energy, Z-30/20 N, and Z-30/20N RJ articulating booms.
- Drop-In Replacement — Matches the original fastener stack-up, so the washer seats correctly against mating hardware without shimming or modification.
- Protects Mating Surfaces — Distributes fastener load across a wider area, preventing surface damage and bolt pull-through in the joint — critical for maintaining the structural integrity of boom-lift assemblies.
- Structural Joint Integrity — A worn, undersized, or missing washer in a boom-lift joint can allow fastener movement and surface fretting; replacing with the correct OEM part restores the joint to its designed clamping condition.
A flat washer serves as a load-distribution interface between a fastener — typically a bolt head or nut — and the surface it clamps against. By spreading the clamping force over a larger area, the washer prevents the fastener from pulling into or damaging the material beneath it and helps maintain consistent clamping tension over time. In boom-lift applications, where structural joints are subject to vibration, dynamic loads, and repeated articulation cycles, using a washer of the correct outer diameter, inner diameter, and thickness is essential; an incorrect washer can allow joint movement, accelerate wear on mating components, and ultimately compromise the security of the assembly.
