The Honda 90091-ZR6-T61 Bolt-Washer (5X155) is a genuine OEM fastener designed for Honda EB-series and EM-series generators, including the EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500. As an OEM component, it is manufactured to the exact dimensions Honda specifies for these generators, ensuring the correct thread engagement and clamping load. When replacing fasteners on your generator, using the correct OEM part keeps the assembly performing as Honda intended and eliminates the guesswork of sourcing a compatible substitute.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt-washer meets the exact dimensional specifications called out for these generator applications, with no risk of mismatched thread pitch or shank length.
- Combined Bolt and Washer Design — the integrated washer flange distributes clamping load evenly across the mating surface, eliminating the need for a separate flat washer during reassembly.
- Broad Generator Fitment — listed for Honda EB3800, EB4000, EB5000, EB6500, EM3800, EM4000, EM5000, and EM6500 generators; verify your generator's serial number against the fitment table to confirm the correct application for your unit.
- Correct Length Matters — at 155 mm, this fastener is a specific-length bolt; confirm the (5X155) specification matches your generator's requirement before ordering, as a shorter or longer bolt can result in improper clamping or thread engagement.
A bolt-washer is a fastener that combines a threaded bolt shank with a captive or integrated washer flange into a single piece. In generator assemblies, fasteners like this one secure major structural or panel components, maintaining the integrity of the overall assembly under the vibration loads that arise during normal operation. When a fastener of this type is missing, damaged, or replaced with an incorrect length or thread specification, it can allow assembled components to shift or work loose over time, leading to noise, misalignment, or more significant service needs.
