The Honda 90157-ZR8-T62 Flange Bolt (6X175) is a genuine OEM component designed for Honda EB and EM series generators. As a direct Honda OEM part, it is manufactured to the same specification as the original hardware installed at the factory, ensuring correct thread engagement and clamping load for your generator. This bolt is listed for EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500 generators — confirm part number 90157-ZR8-T62 against your unit's serial number and parts diagram before ordering, as Honda generators may use different hardware across production runs.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this flange bolt meets the original thread form, shank length, and flange diameter specified for these generators
- Broad EB/EM Series Coverage — listed for EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500 generators, making it a common service item across Honda's conventional generator lineup
- Serial Number Verification Recommended — Honda supersedes hardware at production breaks, so cross-check your generator's serial number against the fitment table to confirm this is the correct bolt for your unit
- Integrated Flange Design — the flange distributes clamping load across a wider bearing surface, reducing the risk of fastener loosening under the vibration loads a running generator produces
A flange bolt combines a standard hex-head bolt with a wide, washer-like flange formed as part of the head. On Honda EB and EM series generators, fasteners like this one are used throughout the assembly to secure structural and mechanical components under the sustained vibration of generator operation. The integrated flange spreads clamping force over a broader contact area compared to a plain bolt, which helps maintain joint integrity over long run times. When a bolt of this type is missing, damaged, or replaced with an incorrect fastener, the joint it secures can work loose, leading to noise, misalignment, or component damage.
