Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this bolt-washer matches the exact dimensions and thread specification Honda requires for these generators.
- Integrated Washer Design — the combined bolt-and-washer construction provides consistent clamping and eliminates the need for a separate washer during assembly.
- Broad Generator Fitment — listed for Honda EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500 generators; verify your serial number against the fitment table, as Honda supersedes hardware at production breaks.
A bolt-washer is a fastener that combines a bolt shank with a captive washer flange at the head. The integrated flange distributes clamping load across a broader surface area than a plain bolt head alone, helping to secure components consistently without requiring a separate loose washer. When the correct fastener is replaced with one of the wrong length or thread pitch, proper clamping cannot be achieved, which can cause panels or components to work loose during generator operation.
