The Genie 1255758GT is a genuine OEM Flat Washer, 3/8, USS, ZAG designed for an exceptionally wide range of Genie equipment, including GS scissor lifts, S and SX series telescopic boom lifts, Z and ZX articulating boom lifts, GTH telehandlers, TZ trailer-mounted booms, and RL series light towers. As a direct OEM replacement sourced through Genie's authorized parts network, this washer is manufactured to the exact material and dimensional standards called out in Genie's parts specifications. Cross-reference part number 1255758GT against your machine's parts manual to confirm the correct application before ordering. With coverage spanning dozens of models across multiple product families, this is a high-utility hardware item to keep on hand for routine service and unplanned maintenance alike.
Key Features
- USS-Grade Zinc-Plated Steel: — The 3/8 USS profile and ZAG (zinc alloy galvanized) finish deliver corrosion resistance suited to outdoor and high-humidity jobsite environments.
- OEM-Spec Load Distribution: — Engineered to the correct outer diameter and thickness for 3/8-inch fastener assemblies, ensuring proper clamping load and surface protection on mating components.
- Drop-In Replacement: — Matches the original Genie specification exactly, so this washer seats and torques correctly without modification to existing hardware or fastener stacks.
- Broad Cross-Family Fitment: — A single part covering GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, GTH telehandlers, TZ trailer booms, and RL light towers makes this a versatile stocking item for mixed Genie fleets.
- Structural Integrity at Every Joint: — A washer in poor condition allows fasteners to loosen, pull through surfaces, or corrode — replacing worn hardware with a correct OEM part maintains the clamping integrity of structural and mechanical joints.
- Genuine OEM Traceability: — Backed by Genie's OEM parts program, this component carries the documentation and part number traceability expected for fleet maintenance records and service compliance.
A flat washer serves a straightforward but critical function: it distributes the clamping force of a bolt or nut across a wider surface area, protecting the material beneath from damage and preventing the fastener from pulling through under load. The USS (United States Standard) sizing designation defines the outer diameter and thickness of the washer relative to its bolt size, ensuring it bears load correctly across a wide variety of structural and mechanical assemblies. When a washer is missing, corroded, or deformed, fastener joints lose clamping consistency — leading to loosening, surface damage, or accelerated wear on surrounding components. Replacing worn or missing washers with the correct OEM specification part is a simple step that supports the long-term integrity of every bolted connection on the machine.
