The Honda 90201-Z6L-010 Special Nut (20MM) is a genuine OEM fastener designed for GX630, GX660, GX690, GX700, GX800, GXV630, GXV660, and GXV690 engines, as well as the EB10000 generator. As a Honda OEM part, this nut is produced to the exact dimensional and mechanical specifications Honda uses in production, ensuring it seats and torques correctly where it is called for. Confirm the part number 90201-Z6L-010 against your machine's Honda parts diagram before ordering, as Honda supersedes fastener specifications at certain serial breaks.
Key Features
- Genuine OEM Specification — sourced directly from Honda, this nut carries the correct 20MM dimensions and thread profile Honda specifies for these engines and generators, not an approximated substitute.
- Broad Fitment Coverage — listed for GX630, GX660, GX690, GX700, and GX800 horizontal shaft engines; GXV630, GXV660, and GXV690 vertical shaft engines; and the EB10000 generator.
- Serial-Range Awareness — Honda updates fastener specifications across production runs; verify your machine's serial number against the fitment table to confirm this is the correct nut for your unit.
- Direct OEM Replacement — installs without modification, matching the original part this nut replaces on the assembly.
A special nut of this size serves as a precision fastener within the engine or generator assembly, providing the clamping force needed to secure a specific component in place at the torque value Honda engineers designed for it. Unlike standard hardware, a "special" designation in Honda's catalogue indicates a unique thread form, shoulder geometry, or seating profile that standard nuts of the same nominal diameter do not replicate. Using the correct OEM nut ensures the fastened joint maintains the integrity Honda intended — an incorrect substitute can result in improper torque retention or component movement over time.
