The Genie 1256182GT Flat Washer, 5/8, F436, HRD, ZAG is a genuine OEM fastener component built for Genie telescopic and articulating boom lifts, including S, SX, Z, ZX, and TZ series machines. As a direct OEM replacement, this washer meets Genie's original material and dimensional specifications, ensuring correct load distribution and clamping performance in bolted connections across the machine. It is confirmed compatible with models including the S-65 XC, S-85 XC, SX-125 XC, Z-62/40, ZX-135/70, TZ-50/30, and additional S, Z, and TZ series machines.
Key Features
- Correct 5/8 Sizing for Direct Replacement — The 5/8-inch flat washer dimensions ensure proper load-bearing surface area and correct fit under fastener heads or nuts without modification.
- Broad Boom Lift Compatibility — Fits a wide range of Genie telescopic booms (S and SX series), articulating booms (Z, ZX, and Z XC series), and trailer-mounted booms (TZ series).
- Protects Mating Surfaces — A properly rated hardened washer prevents fastener pull-through and surface damage at high-load connection points, maintaining joint integrity over the machine's service life.
- Genuine Part for Structural Confidence — On elevated aerial work platforms, fastener hardware at structural joints is a critical element. Using the correct OEM-specified washer supports the integrity of bolted assemblies throughout the boom structure.
A flat washer distributes the clamping load of a bolt or nut across a wider surface area, preventing damage to the material being fastened and reducing the risk of fastener loosening under vibration or dynamic loading. The F436 designation indicates a structural-grade hardened washer, meaning it is rated for use in high-load bolted connections where softer hardware would deform or allow joint slippage. When a washer of this type wears, corrodes, or is replaced with an incorrect grade, the fastener assembly loses its rated clamping capacity — potentially allowing movement or fatigue at critical structural joints on the boom lift.
