The Honda 90103-ZA1-811 Hexagon Bolt (6X30) is a genuine OEM fastener designed for Honda EW140, EW170, EW171, and EXW171 welder generators. As an OEM component sourced directly from Honda, this bolt is manufactured to the exact dimensions and specifications used in original production — ensuring a correct fit when replacing worn, stripped, or missing hardware. Honda supersedes fasteners at serial breaks, so confirm your unit's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, matching the original bolt specification used on these welder generators at the time of manufacture
- Exact Dimensional Fit — the 6x30 sizing is specific to this application; using an incorrect bolt length or thread pitch can result in improper clamping or thread damage
- Broad Welder Generator Coverage — listed for the EW140, EW170, EW171, and EXW171, including the full Honda EW and EXW welder generator lineup
- Serial Number Verification Recommended — Honda updates hardware specifications across production runs, so check your serial number against the compatibility table to confirm this is the correct bolt for your unit
A hexagon bolt is a standard threaded fastener used throughout the assembly of Honda welder generators to clamp and secure components at precise torque values. The 6x30 designation refers to the bolt's thread diameter and shank length, both of which must match the original specification exactly — an undersized or oversized bolt will not achieve proper clamping force and can work loose under the vibration and load cycles a welder generator encounters in regular use. Replacing a stripped or damaged bolt with the correct OEM part restores the integrity of the fastened joint and keeps the assembly secure during operation.
