The Honda 90201-836-000 Special Nut (14MM) is a genuine OEM component designed for E300, EM400, and ER400 generators. As a Honda original part, it is manufactured to the same specifications as the hardware installed at the factory, ensuring correct thread engagement and proper clamping force for the application. This Special Nut (14MM) is listed for the E300, EM400, and ER400 — confirm your generator's model and serial number against the fitment table before ordering, as Honda periodically updates hardware at production serial breaks.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this nut meets the exact thread and dimensional specification Honda applied to E300, EM400, and ER400 generators at the point of manufacture.
- Correct 14MM Sizing — the 14MM designation is integral to this part; using an incorrect size risks improper torque and compromised fastening, so match this specification to your generator's requirement before installation.
- Generator Fitment — listed for E300, EM400, and ER400 Honda generators; check your serial number against the compatibility table to confirm this is the correct part for your specific unit.
A special nut differs from a standard hex nut in geometry or thread form, and Honda designates it as such because a generic substitute of the same nominal size may not engage correctly or deliver the clamping retention the application requires. In a generator, fasteners of this type secure components subject to continuous vibration during operation, and a nut that does not seat or torque correctly can work loose over time. Using the correct Honda OEM part number 90201-836-000 ensures the thread form, bearing face, and dimensions match exactly what the generator was designed to accept.
