Key Features
- Genuine OEM Hardware — manufactured to Honda's original thread and flange specifications, not a generic substitute that may differ in clamping dimensions
- Integrated Flange Design — the built-in flange distributes clamping load evenly, eliminating the need for a separate washer and maintaining consistent fastener retention over repeated service cycles
- Broad Generator Fitment — listed for Honda EB11000, EB12, EM1800, EM2200, EM2500, EM3500, EM5000, EX3300, EX4500, and EX5500 generators; check your serial number against the fitment table to confirm applicability to your specific unit
- Direct Service Replacement — matches the original part exactly, allowing straightforward installation during routine maintenance or repair without modification
A flange nut is a standard threaded fastener with an integrated wide-diameter collar on one face that acts as a built-in washer. In Honda generators, small hardware like this 3MM Flange Nut secures panels, brackets, and internal components in place during operation. When a fastener of this type is missing, damaged, or replaced with an incorrect substitute, the clamping force at that joint is compromised, which can allow components to shift or loosen under the vibration loads a running generator produces. Using the correct Honda OEM replacement restores the joint to its designed holding capacity.
