The Honda 90501-ZS2-H61 Plain Washer (21MM) is a genuine OEM component designed for EZ1400 and EZ2500 generators. As a factory-sourced part, this washer matches Honda's original specifications for correct load distribution and secure fastener retention on these generators. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at defined serial breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring the correct 21MM diameter for an exact match to original hardware on EZ1400 and EZ2500 generators
- Correct Load Distribution — a properly sized washer spreads clamping force evenly across the mating surface, preventing fastener pull-through and surface damage over time
- Serial Number Matters — Honda updates hardware specifications at production breakpoints, so verify your generator's serial number against the compatibility table to confirm this is the right washer for your unit
A plain washer serves as a bearing surface between a fastener — such as a bolt or nut — and the component it clamps. By distributing the fastener's clamping load over a wider area, it prevents the hardware from digging into or distorting the surface below. Using a washer of the correct diameter and thickness keeps fastener assemblies secure under the vibration and load cycles that generators experience in regular use. An incorrect or missing washer can lead to fastener loosening or localized surface wear over time.
