The Honda 90101-ZB3-C01 Flange Bolt (8X185) is a genuine OEM fastener designed for Honda EB, EG, and EM series generators. As a direct Honda OEM part, it is manufactured to the exact dimensions required for proper clamping and assembly integrity across the generator models it serves. Fitment spans a wide range of Honda generators, including the EB2200, EB2500, EG1400, EG2200, EG2500, EM1600, EM1800, EM2200, and EM2500 — always confirm your unit's model number before ordering, as Honda supersedes hardware at production breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt meets the exact dimensional and mechanical requirements Honda specified for these generator assemblies, ensuring proper clamping force and fit.
- Correct Length and Flange Geometry — the 8X185 sizing is specific to this application; using an incorrect length or a standard bolt without the integrated flange can result in improper clamping and assembly issues.
- Broad Generator Compatibility — listed for Honda EB2200, EB2500, EG1400, EG2200, EG2500, EM1600, EM1800, EM2200, and EM2500 generators; check your model and serial number against the fitment table to confirm the correct bolt for your unit.
- Serial Number Verification Recommended — Honda updates hardware specifications at production serial breaks, so matching your generator's serial number to the fitment table is the surest way to confirm part number 90101-ZB3-C01 is right for your machine.
A flange bolt combines a standard hex bolt with an integrated flanged washer at the bearing face. The flange distributes clamping load over a wider surface area than a plain bolt head alone, reducing the risk of surface damage and maintaining consistent clamp force across the joint. In generator assemblies, where components must remain securely fastened through sustained vibration and varying thermal cycles, using the correct OEM bolt — with the right length, thread pitch, and flange diameter — keeps the assembly performing as Honda designed it.
