Key Features
- Genuine OEM Material Grade — Nylon construction delivers the correct compression resistance and insulating properties for this washer's role, meeting Genie's dimensional spec of .515x.88x.093 exactly.
- Exact Dimensional Fit — The .515x.88x.093 specification matches the original precisely, seating correctly against mating hardware without modification.
- Broad Equipment Compatibility — Fits multiple Genie equipment families including light towers, scissor lifts, telescopic booms, personnel lifts, and material lifts.
- Protects Mating Surfaces — Nylon distributes load evenly and resists galvanic interaction between dissimilar metals, extending the service life of the hardware it supports.
- OEM Sourcing Confidence — Supplied as a genuine Genie part through DHS Equipment, so the specification, material, and part number are verified against the original design.
A flat washer distributes the clamping load of a bolt or fastener across a wider surface area, protecting the material beneath from damage and preventing the fastener from pulling through under load. Nylon flat washers also provide a degree of electrical insulation and reduce wear between dissimilar materials. When a washer is undersized, deformed, or missing, fasteners can loosen over time or cause surface damage — replacing a worn washer with the correct OEM item keeps the joint secure and performing as designed.
