The Honda 90202-ZA0-000 Lock Nut (30MM) is a genuine OEM fastener designed for Honda GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, EV4010, EV6010, and EVD4010 RV generators, and H4514, HT3813, and HT4213 lawn tractors. As a genuine Honda part, it is manufactured to the exact specifications required for proper clamping retention in each application. Verify your machine's serial number against the fitment table to confirm this is the correct lock nut for your unit before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, ensuring the correct 30MM thread specification and locking geometry for secure, lasting retention
- Broad Application Coverage — listed for GX360 engines, EL5000, ES6500, and EX5500 generators, EV-series RV generators, and H4514, HT3813, and HT4213 lawn tractors, including part number 90202-ZA0-000
- Serial Number Verification Recommended — Honda supersedes fastener part numbers at production breaks; check your serial number against the fitment table to confirm the correct part for your specific unit
- Consistent Clamping Performance — the locking feature resists loosening under the vibration loads these engines, generators, and tractors generate during normal operation
A lock nut is a fastener designed to resist loosening once torqued into position. Unlike a standard nut, its locking feature — whether a nylon insert, a distorted thread, or a prevailing-torque profile — grips the mating thread and holds clamping force even when the assembly is subject to vibration or cyclical loading. In engines, generators, RV generators, and lawn tractors, fasteners in high-vibration zones can gradually back off if a standard nut is used; the lock nut prevents this, keeping critical components secured as intended. A worn or damaged lock nut that no longer holds its locking force should be replaced rather than reused to maintain the integrity of the assembly.
