The Honda 90157-ZD1-E31 Flange Bolt (6X175) is a genuine OEM Flange Bolt (6X175) designed for the EB6500 and EM6000 generators and the EW171 welder generator. As a direct Honda OEM part, it meets the original specifications set for these machines, ensuring correct fit without guesswork. Honda supersedes hardware at production breaks, so confirm the serial number on your unit against the fitment table before ordering to make sure part number 90157-ZD1-E31 is the right bolt for your application.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this bolt matches the thread pitch, shank length, and flange diameter specified for the original build.
- Correct 6X175 Specification — the (6X175) designation identifies the exact bolt size; verify this matches the fastener position on your machine before ordering.
- Generator and Welder Generator Fitment — listed for EB6500 and EM6000 generators and the EW171 welder generator; check your serial number against the fitment table to confirm applicability.
- Serial-Range Awareness — Honda updates hardware specifications at serial breaks, so always cross-reference your machine's serial number with the compatibility table to avoid ordering the wrong variant.
A flange bolt combines a conventional bolt with an integrated washer-like flange beneath the head. The flange distributes clamping load across a wider surface area than a standard bolt head, reducing the chance of fastener loosening under vibration — a real concern on generator and welder generator frames that experience continuous engine-driven vibration during operation. When a flange bolt is missing or incorrectly specified, the clamping force at that joint is compromised, which can lead to movement, wear, or damage at the fastened connection over time.
