The Honda 90103-Z33-V20 Flange Bolt (6X25) is a genuine OEM Flange Bolt designed for the EG4000 generator. As a factory-sourced fastener, this bolt is manufactured to Honda's exact dimensions, thread pitch, and head geometry — ensuring the correct clamp load without the guesswork that comes with non-OEM substitutes. When you order part number 90103-Z33-V20 from DHS Equipment, you receive the same hardware Honda installs at the factory, matched precisely to the EG4000.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt meets the exact thread pitch, shank length, and flange diameter specified for the EG4000 generator
- Exact Replacement — drops in as a direct swap with no modification, maintaining proper clamp load and alignment where it is installed
- Serial Number Verification — Honda updates part supersessions at specific serial breaks; confirm your EG4000 serial number against the fitment table before ordering to ensure this is the correct bolt for your unit
A flange bolt combines a standard hex bolt with an integrated flange that distributes clamping force over a wider surface area than a plain bolt and separate washer. On the EG4000 generator, this design helps maintain consistent fastening tension across the service life of the machine. A worn, stripped, or incorrect-length bolt in this application can result in loose assemblies, vibration-related damage, or loss of a secure joint — making like-for-like OEM replacement the straightforward choice when servicing this generator.
