The Honda 90157-ZR6-T61 Flange Bolt (6X120) is a genuine OEM fastener designed for Honda EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500 generators. As an authentic Honda part, it meets the same standards as the original hardware installed on these generators at the factory. Replacing worn or damaged fasteners with the correct OEM specification hardware is the surest way to maintain proper clamping force and keep your generator running as intended. Always cross-reference the part number 90157-ZR6-T61 with your generator's serial number to confirm this is the right bolt for your specific unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt matches the original specification for correct thread engagement and clamping load on these generators
- Integrated Flange Design — the built-in flange distributes clamping force over a wider bearing surface compared to a standard bolt head, reducing the chance of fastener loosening under vibration
- Broad Generator Fitment — listed for the EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500; verify your serial number against the fitment table before ordering
- Exact Dimensions — the 6X120 designation identifies the thread diameter and length; using the correct size ensures proper thread depth and prevents under- or over-penetration in the fastened joint
A flange bolt combines a standard hex bolt with a wide, washer-like flange beneath the head. On generators like these Honda EB and EM models, flange bolts are used where a broad clamping surface is needed or where a separate washer would be impractical. The integrated flange spreads the load across a larger area, which helps maintain joint integrity even when the generator is running under load and producing constant vibration. A bolt that is the wrong length, the wrong thread pitch, or simply worn and stretched will not hold the joint correctly, which can lead to loosening over time.
