Key Features
- Genuine OEM Hardware Integrity — Sourced directly from Genie, this lock washer meets the exact material hardness and dimensional tolerances required for M12 fastener assemblies on boom lift structures.
- Drop-In M12 Compatibility — Sized to seat correctly on M12 fastener threads, this washer installs directly in place of the original with no modification to surrounding hardware or mounting surfaces.
- Broad Boom Lift Coverage — Fits a wide range of Genie telescopic booms (S series), articulating booms (Z-80/60), and trailer-mounted booms (TZ-34/20, TZ-50, TMZ-34/19), making it a practical stocking item for mixed Genie fleets.
- Prevents Fastener Loosening Under Load — Lock washers resist vibration-induced loosening in structural and mechanical assemblies. A missing or flattened washer can allow critical fasteners to back out during operation, leading to component shift or mechanical failure.
- Structural Safety Relevance — On aerial boom lifts, fastener integrity in boom, turntable, and outrigger assemblies directly affects platform stability. Replacing worn or missing lock washers with the correct OEM part supports the mechanical reliability these machines depend on at height.
A lock washer is a hardened ring-shaped fastener component placed beneath a nut or bolt head to prevent loosening caused by vibration, dynamic loading, or thermal cycling. On boom lifts — which are subject to continuous movement, extension cycles, and variable loads — maintaining fastener torque retention throughout structural and mechanical assemblies is critical. When a lock washer flattens, cracks, or goes missing, the fastener it secures can gradually back out, potentially allowing connected components to shift or fail; replacing it with the correct M12 part restores the clamping integrity of the assembly.
