The Honda 90201-Z2E-000 Special Nut (16MM) is a genuine OEM fastener designed for GX440 horizontal shaft engines. As a direct Honda OEM component, this nut is manufactured to the exact dimensional and mechanical specifications Honda requires for the GX440. Confirm your engine's serial number against the fitment table before ordering to ensure this is the correct variant for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this nut meets the exact specifications called out in the GX440 parts catalog, so there is no guesswork on sizing or thread form.
- Correct 16MM Sizing — the 16MM designation identifies this as a specific variant; always match it to the application shown in your engine's parts diagram before installing.
- GX440 Fitment — listed for GX440 horizontal shaft engines; check your serial number against the fitment table, as Honda updates part numbers at production breaks.
A special nut differs from a standard hex nut in that Honda has engineered it with specific geometry — such as a modified flange, shoulder, or thread form — to suit a particular clamping or retention requirement within the GX440 engine. Using the correct Honda OEM nut ensures the proper clamping load and thread engagement are maintained. Substituting an incorrect fastener can result in improper torque retention or fitment issues that affect the reliability of the assembly it secures.
