The Honda 90401-ZG5-000 Plain Washer (12MM) is a genuine OEM component designed for EB12 generators and H6522 compact tractors. Sourced directly from Honda, this washer meets the same standards as the part originally installed at the factory. Because Honda supersedes parts at serial-number breaks, confirm your machine's serial number against the fitment table before placing your order. Having the correct 12mm plain washer on hand keeps service work moving without delays caused by incorrect hardware.
Key Features
- Genuine OEM Honda Part — sourced directly from Honda, ensuring the 12mm dimensions and load-bearing characteristics match the original hardware specification
- Broad Application Coverage — listed for EB12 generators and H6522 compact tractors, covering two distinct Honda equipment classes with a single part number 90401-ZG5-000
- Serial Number Verification Advised — Honda updates hardware specifications at production breaks, so check your unit's serial number against the fitment table to confirm this is the correct washer for your machine
A plain washer distributes the clamping load of a fastener across a broader surface area, preventing the bolt head or nut from pulling into or damaging the material being secured. In equipment such as generators and compact tractors, correctly sized washers are essential wherever fastener load needs to be spread evenly — an undersized or worn washer can allow fasteners to work loose over time, leading to vibration-related damage at the joint. Using the correct 12mm washer ensures the fastener assembly holds its specified torque throughout the service life of the equipment.
