The Honda 90051-883-000 Screw-Washer (5X12) is a genuine OEM fastener used across a wide range of Honda generators, tillers, horizontal and vertical shaft engines, lawn mowers, snow blowers, and water pumps. As an OEM part sourced directly through Honda's parts catalogue, this screw-washer is the same hardware specified for original assembly, ensuring the correct thread engagement and clamping characteristics for the applications it serves. This component is listed for models including the E1500, E2500, E3500, EB3000, EB4000, ED1000, EG1000, EG1400, EG1500, EG2200, EM1600, ES3500, EW170, F200, F400, F500, FR500, FR700, G100, G150, G200, G300, GV150, GV200, GV400, HR17, HR21, HRA21, HS35, HS50, HS70, WA15, WA20, WA30, WB15, WT20, and WT30 — verify your model and serial number against the fitment table before ordering.
Key Features
- Genuine OEM Honda Hardware — supplied to Honda's original assembly specification, so thread form, shank diameter.
- Broad Cross-Equipment Fitment — listed for Honda generators, tillers, engines, lawn mowers, snow blowers, and water pumps; confirm your specific model against the compatibility table
- Serial Number Verification Recommended — Honda updates fastener part numbers at production breaks, so always cross-reference your machine's serial number with the fitment table to confirm this is the correct screw-washer for your unit
- Integrated Washer Design — the captive washer distributes clamping load evenly, reducing the chance of surface damage or fastener back-out over the service life of the assembly
A screw-washer is a fastener that combines a machine screw with a permanently attached washer flange at the head. The integrated washer spreads the clamping force over a wider area than a plain screw head alone, helping to secure panels, covers, and components without concentrating stress on the mating surface. When a screw-washer loosens, backs out, or is missing, the part it retains can shift, vibrate free, or allow contaminants to enter — making timely replacement with the correct OEM hardware important to keeping the assembly intact.
