Key Features
- Genuine OEM Honda Hardware — manufactured to Honda's own dimensional specifications, ensuring correct thread engagement and clamping load for the application.
- Broad Generator Compatibility — listed for Honda E1500, EM1600, EM1800, EM2200, EM3000, EM4000, EMS4000, EMS4500, EW140, EW170, EW171, and EXW171 generators and welder generators.
- Serial Number Verification Recommended — Honda supersedes fastener part numbers at production breaks; confirm your unit's serial number against the fitment table to ensure this is the correct nut for your machine.
A 5MM hexagon nut is a standard threaded fastener used to clamp and secure components within the generator assembly. When the correct nut is in place and properly torqued, it maintains consistent clamping force that keeps panels, brackets, and internal components firmly positioned during operation. Using the wrong fastener — one with an incorrect thread pitch or a smaller load rating — risks loosening over time under the vibration a running generator produces, which can lead to misaligned components or stripped threads.
