The Honda 90004-GHB-640 Flange Bolt (6X18) is a genuine OEM fastener designed for the EU3200 inverter generator. As a factory-sourced component, this bolt meets Honda's original specifications for the EU3200, ensuring the correct thread pitch, shank length, and flange diameter. When a fastener on your generator strips, loosens, or goes missing, replacing it with the correct OEM part keeps the assembly secure and properly torqued.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt carries the correct 6 mm thread diameter and 18 mm shank length specified for the EU3200 inverter generator
- Integrated Flange Design — the built-in flange distributes clamping load evenly, eliminating the need for a separate washer and maintaining consistent holding force at the joint
- Exact Replacement — matches the original part number 90004-GHB-640 for a direct swap with no rework or substitution required
- Verify Your Serial Number — Honda updates parts at specific serial breaks, so confirm your EU3200 serial number against the fitment table before ordering
A flange bolt is a hex-head fastener with a wide, integrated washer-like flange formed at the base of the head. The flange spreads the clamping force over a broader surface area than a standard hex bolt, reducing the risk of loosening under vibration — a common condition in generator operation. Using the correct OEM bolt ensures the thread engagement, flange diameter, and torque retention all match what Honda engineered for the EU3200 assembly point.
