As a direct Honda OEM part, this washer is manufactured to the exact dimensions specified for these machines, ensuring proper fit without any guesswork. Verify your machine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one variant may be listed for a given model.
Key Features
- Genuine OEM Sizing — produced to Honda's exact 8.5MM bore specification, so the washer seats and clamps correctly without shimming or modification
- Broad Model Coverage — listed for Honda H4013, H4514, H4518, HT3813, and HT4213 lawn tractors, as well as HS522 and HS622 two-stage snow blowers
- Serial Number Verification Recommended — Honda updates part numbers at serial breaks, so confirm your machine's serial number against the fitment table to ensure this is the correct washer for your unit
A plain washer distributes the clamping load of a fastener across a wider surface area, preventing the bolt head or nut from pulling through or damaging the surrounding material. On lawn tractors and snow blowers, washers like this one appear throughout the machine wherever consistent fastener tension needs to be maintained. A missing or incorrect washer can allow fasteners to loosen over time, leading to unwanted play in assembled components.
