The Genie 19872GT is a genuine OEM Lock Washer, M5, Plated designed for a wide range of Genie GS scissor lifts, S series telescopic boom lifts, and TMZ trailer-mounted articulating booms. Sourced directly from Genie, this lock washer matches the exact material, plating, and dimensional spec of the original hardware installed at the factory. Compatible models include the GS-1530, GS-1930, GS-2046, GS-2646, GS-3246, GS-3384, GS-3390, GS-4390, GS-5390, S-40, S-45, TMZ-50/30, TMZ-34/19, and TMZ-17/10. When it comes to threaded fasteners on aerial equipment, using the correct OEM hardware is the straightforward choice for maintaining the integrity of every bolted connection.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Genie's exact M5 plating and material spec, ensuring consistent clamping force and corrosion resistance across every application.
- Direct Drop-In Replacement — Sized and profiled to seat correctly on M5 fasteners as originally assembled, requiring no rework of mating hardware or mounting surfaces.
- Broad Genie Fitment — Fits GS scissor lifts from the GS-1530 through GS-5390, S series telescopic booms including the S-40 and S-45, and TMZ trailer-mounted articulating booms.
- Protects Fastener Integrity — The lock washer's spring action resists loosening from vibration and dynamic loads — a critical function on aerial equipment that cycles and travels regularly.
- Corrosion-Resistant Plating — The plated finish provides an added barrier against moisture and environmental exposure, extending the service life of the fastener assembly in outdoor or harsh-site conditions.
- Structural Connection Compliance — On aerial lifts, a loose or missing lock washer in a structural or safety-critical joint can allow bolt movement that compromises the connection over time; replacing worn hardware with the correct OEM part maintains the designed clamping integrity.
A lock washer is a thin, hardened ring installed beneath a nut or bolt head to prevent the fastener from backing out under vibration, shock loads, or repeated movement. On aerial work platforms and boom lifts, threaded connections are subject to constant dynamic stress as the machine travels, extends, and retracts — making proper fastener retention essential. When a lock washer flattens, fractures, or is missing entirely, the fastener can lose clamp load and allow joint movement that accelerates wear or leads to loosening in structural assemblies. Replacing it with the correct OEM part restores the clamping system to its original specification.
