The Genie 59672GT is a genuine OEM Internal Star Washer designed for Genie GS scissor lifts and TZ and TMZ trailer-mounted articulating booms. As a factory-authorized replacement, this washer meets the same specifications as the hardware installed at the time of manufacture, ensuring a correct and consistent fit within its intended assembly. It is compatible with a wide range of units including the GS-3384, GS-3390, GS-4390, GS-5390, TZ-50/30, TZ-50, TMZ-34/19, TMZ-50/30, and TMZ-17/10. Cross-reference part number 59672GT against your Genie parts manual to confirm fitment before ordering.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to the same grip and locking specifications as the original, ensuring consistent clamp load and vibration resistance in the intended fastener assembly.
- Direct-Fit Replacement — Drops straight into the existing fastener stack without rework, matching the original washer's bore diameter and tooth profile exactly as assembled at the factory.
- Broad Genie Fitment — Fits Genie GS large-platform scissor lifts and TZ and TMZ trailer-mounted articulating boom models, covering a wide cross-section of the Genie aerial equipment fleet.
- Secure Fastener Locking — Internal teeth bite into the mating surface under torque, maintaining bolt tension in assemblies subject to vibration and repeated load cycles — critical for structural and mechanical connections on aerial equipment.
- Operational Safety Assurance — On aerial lifts, fastener hardware that loses preload due to vibration can compromise structural integrity; using the correct OEM washer helps maintain the clamping force that holding-critical joints depend on.
An internal star washer is a hardened locking washer with inward-facing teeth arranged around its inner diameter. When a bolt or screw is tightened, the teeth bite into both the fastener head or nut and the mating surface, creating mechanical resistance that prevents the fastener from backing out under vibration or dynamic loading. On aerial work platforms and trailer-mounted booms — machines that travel over uneven terrain and flex under load — maintaining bolt preload throughout the service life of a joint is essential. When a star washer flattens, corrodes, or goes missing, the fastener it was securing becomes vulnerable to loosening, which can affect the function and structural integrity of the surrounding assembly.
