The Honda 94050-10080 Flange Nut (10MM) is a genuine OEM fastener used across a wide range of Honda engines, power equipment, and outdoor power machinery. This 10MM flange nut is sourced directly from Honda and spans an exceptionally broad fitment range, including GX200 and G400 horizontal shaft engines, GV400 vertical shaft engines, EU1000 and EU7000 inverter generators, EB and EM-series generators, FR-series tillers, H-series lawn and multi-purpose tractors, HR-series walk-behind mowers, and EW170 welder generators, among others. Because this nut appears across so many platforms, confirm part number 94050-10080 against your machine's serial number and Honda parts diagram before ordering. As a genuine Honda OEM component, this Flange Nut (10MM) is made to Honda's original design and dimensions, ensuring it threads and seats correctly in the application it was engineered for.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, matching the exact dimensions, thread pitch, and flange geometry of the original nut installed at the factory.
- 10MM Flange Design — the integrated flange distributes clamping load evenly across the mating surface, eliminating the need for a separate washer in applications where it is used.
- Exceptionally Wide Fitment — fits an extensive range of Honda equipment including GX200 engines, GV400 engines, EU and EB-series generators, FR-series tillers, H-series tractors, and HR-series walk-behind mowers, including the HRN216, HRR216, and HRX217.
- Verify Your Serial Number — Honda supersedes fasteners across production runs; check your machine's serial number against the fitment table to confirm this nut is correct for your specific unit before installing.
A flange nut is a standard hex nut with a wide, integrated flange on one face that acts as a built-in washer. The flange spreads the clamping force over a larger surface area than a plain nut would, helping to secure fastened components firmly and evenly without requiring a separate washer. When a flange nut loosens, stretches, or strips, it can allow the components it secures to shift or separate, leading to vibration, misalignment, or mechanical failure in the assembly it holds together. Replacing a worn or damaged nut with the correct genuine OEM part restores proper clamping load and keeps the fastened joint secure through normal operating conditions.
