Key Features
- OEM Dimensional Conformity — Manufactured to Genie's exact 1.56 x 2.5 x .061 specification, ensuring correct bearing surface area and thickness for the fastener assemblies it supports.
- Direct OEM Replacement — Drops into place wherever the original washer is fitted, with no reworking or adaptation needed at the joint.
- Broad Boom Lift Fitment — Fits a wide range of Genie S series telescopic and Z series articulating boom lifts, including the S-80, S-85 XC, SX-180, Z-135/70, and ZX-135/70.
- Correct Load Distribution — A properly sized flat washer spreads clamping load evenly across the mating surface, protecting fastener integrity and the surrounding material from deformation over time.
- Genuine Genie Part — Supplied as a genuine OEM component, giving you confidence that the material grade and dimensions match the original part exactly.
A flat washer sits between a fastener — such as a bolt head or nut — and the surface it clamps against. Its job is to spread the clamping force over a wider area, reducing the risk of the fastener pulling through or damaging the material underneath. The 1.56 x 2.5 x .061 dimensions are specific to this application: an incorrect washer that is too thin, too narrow, or oversized can allow fasteners to loosen under load or concentrate stress in the wrong place. Replacing a worn, deformed, or missing flat washer with the correct OEM part restores the joint to its original clamping integrity and helps keep the surrounding hardware secure during operation.
