Key Features
- Correct M4 Sizing — Sized at M4 to match the original fastener specification exactly, ensuring a proper seating fit on the correct fastener without shimming or modification.
- Genuine OEM Quality — Sourced directly from Genie as an OEM part, holding the dimensional conformity and material grade of the original component it replaces.
- Broad Z-Series Compatibility — Confirmed fitment across multiple Genie Z-series articulating boom lift models, from the Z-45/25 IC through to the Z-135/70 and ZX-135/70.
- Secure Fastener Retention — A functioning lock washer resists loosening caused by vibration and movement; a damaged or missing one allows fasteners to back out, compromising the integrity of the assembly it secures.
A lock washer is a thin, hardened ring placed beneath a nut or bolt head to grip both the fastener and the mating surface, resisting the rotational loosening that vibration and dynamic loads cause over time. On articulating boom lifts — machines that experience constant movement, extension cycles, and varying loads — keeping fasteners torqued and secure is critical to structural and mechanical integrity. A missing, cracked, or deformed lock washer allows fasteners to back out gradually, which can lead to loose assemblies and unplanned maintenance. Replacing a worn washer with the correct OEM part restores the clamping arrangement to its original specification.
