The Genie 01.0031.0061GT Flat Washer D20 UNI 6592 ZN is a genuine OEM zinc-plated fastener component designed for Genie GTH telehandlers and select articulating boom lift models. Sourced directly through Genie's OEM supply chain, this washer meets the UNI 6592 standard and carries a zinc (ZN) finish for corrosion resistance in demanding jobsite conditions. This part fits a wide range of GTH telehandler variants — including the GTH-5519, GTH-4014, GTH-4018, GTH-4016R, GTH-1256, GTH-1544, GTH-2506, GTH-3007, GTH-3512, GTH-3713, and GTH-5021 series — as well as the Z-33/18 and Z-33 DC Power articulating booms. Cross-reference part number 01.0031.0061GT against your Genie parts manual to confirm fitment for your specific unit.
Key Features
- Genuine OEM Construction — Manufactured to Genie's UNI 6592 standard with a zinc finish, ensuring the washer delivers the correct load distribution and surface contact geometry for bolted joints across GTH telehandler assemblies.
- Direct Drop-In Replacement — This washer installs exactly as the original, maintaining proper clamp load and hardware stack-up without rework or shimming.
- Broad GTH Telehandler Coverage — Fits an extensive range of Genie GTH telehandler variants spanning IIIA, IIIB, AU, AF, ACF, FMS, R, and SX configurations, plus the Z-33/18 and Z-33 DC Power articulating booms.
- Zinc-Plated for Corrosion Resistance — The ZN (zinc) plating helps the washer withstand moisture and outdoor exposure, supporting hardware longevity in rough-terrain and all-weather telehandler applications.
- Critical Fastener Integrity — Using the correct OEM washer maintains proper torque retention and joint clamping in structural and mechanical connections — an important consideration for telehandler boom and frame fastener systems where hardware integrity affects safe operation.
A flat washer distributes the clamping force of a bolt or nut across a wider surface area, preventing the fastener from pulling through or damaging the material it secures. In heavy equipment like telehandlers, washers also protect softer mounting surfaces and help maintain consistent torque settings over time. When a washer is missing, undersized, or of the wrong specification, bolted joints can loosen prematurely or concentrate stress unevenly — potentially compromising the integrity of critical structural and mechanical connections on the machine.
