The Genie 1255758GT Flat Washer, 3/8, USS, ZAG is a genuine OEM fastener built for a broad range of Genie equipment, including GS scissor lifts, S and SX telescopic boom lifts, Z and ZX articulating boom lifts, TZ trailer-mounted booms, GTH telehandlers, and RL vertical mast units. As a direct OEM replacement, it meets Genie's original dimensional and material specifications without any modification. Cross-reference part number 1255758GT against your machine's parts manual to confirm it is the correct item for your application before ordering.
Key Features
- Genuine OEM Construction — Zinc-coated (ZAG) USS-standard flat washer manufactured to Genie's original dimensional tolerances, ensuring correct seating and load distribution at the fastening point.
- Direct OEM Replacement — Matches the original 3/8 USS specification exactly, dropping into place without rework or adaptation.
- Wide Equipment Compatibility — Fits GS scissor lifts, S and SX telescopic booms, Z and ZX articulating booms, TZ trailer-mounted booms, GTH telehandlers, and RL vertical mast lifts across the Genie lineup.
- Zinc-Coated Finish for Durability — The ZAG zinc finish provides a barrier against corrosion, helping the washer maintain clamping integrity in outdoor and variable-weather jobsite conditions.
- Correct Load Spreading — A properly fitted flat washer distributes fastener load evenly across the mating surface, protecting against fastener pull-through and preserving the integrity of the joint over time.
A flat washer is placed under a bolt head or nut to spread the clamping load across a wider surface area, preventing damage to the material being fastened and maintaining consistent joint tension. The USS designation defines the washer's outer diameter and thickness to a standardized series, ensuring it fits correctly with the corresponding 3/8 fastener. When a washer is missing, undersized, or damaged, the fastener can loosen, the mating surface can deform, and the connection can fail — making it important to replace any worn or lost washer with the correct OEM part.
