The Honda 90428-844-650 Washer (8MM) is a genuine OEM replacement designed for a wide range of Honda generators, tillers, and single-stage snow blowers, including the E900, F28, F400, F401, F500, F501, FC600, FG400, FG500, FR500, FR600, FR650, FR700, FR750, FR800, HS35, HS520, HS521, HS621, and HS720. As a Honda OEM component, this washer is produced to the same specifications as the original part fitted at the factory. Because this washer is listed across multiple machine families, confirm your model and serial number against the fitment table before ordering to ensure you are selecting the correct part for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original specification and dimensions for the models it covers.
- Direct Fit — manufactured to the exact tolerances Honda requires, so this part drops in without modification.
- Broad Coverage — listed for Honda E900 generators, F-series and FG/FR-series tillers, and HS-series single-stage snow blowers, including the HS35, HS520, HS521, HS621, and HS720.
- Serial Number Verification Recommended — Honda supersedes parts across production runs, so check your machine's serial number against the fitment table to confirm part number 90428-844-650 is correct for your specific unit.
An 8MM washer serves as a load-distributing fastener component, spreading clamping force evenly beneath a bolt or nut head to protect the mating surface and maintain secure assembly. When a washer of this size is missing or damaged, fastener assemblies can loosen over time under vibration and operating loads, leading to mechanical play or component wear at the joint. Replacing a worn or missing washer with the correct OEM part restores the integrity of the fastened connection and helps keep the surrounding hardware seated properly through normal service.
