As a direct Honda OEM part, it is manufactured to the same specifications as the original hardware used on the production line.

Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt matches the original fastener in thread pitch, shank length, and flange geometry for a true like-for-like replacement
- Integrated Flange Design — the built-in flange distributes clamping load evenly across the mating surface, eliminating the need for a separate washer
- Broad Generator Fitment — listed for Honda EB4000, EB5000, EB6500, EM4000, EM5000, and EM6500 generators; verify your serial number against the fitment table to confirm the correct application
- Exact Replacement — Honda supersedes hardware at production breaks, so cross-check part number 90101-Z23-F10 against your generator's serial number before installing
A flange bolt combines a standard hex bolt with an integral flanged bearing surface directly beneath the head. This flange acts as a built-in washer, spreading the clamping force over a wider area to reduce the risk of surface damage and maintain consistent joint tension. In generator applications, proper clamping is essential to keeping assemblies secure under the vibration loads that come with continuous operation — a loose or incorrect fastener can allow components to shift and cause secondary damage over time.
