Key Features
- Genuine OEM Dimensioning — manufactured to Honda's exact 5.2 x 17 mm specification, delivering the correct load distribution and seating required for this application
- Direct OEM Replacement — sourced directly from Honda, this washer installs without modification and restores the assembly to its original condition
- Generator Fitment — listed for EM650 and EX650 generators; verify your serial number against the fitment table to confirm the correct part for your unit
A washer serves as a load-distributing interface between a fastener and the surface it bears against, spreading clamping force evenly and protecting the mating surface from damage. In a generator like the EM650 or EX650, washers appear throughout the assembly wherever fasteners must seat securely without distorting or gouging softer components. Using a washer of the wrong diameter or thickness can result in uneven clamping, fastener loosening under vibration, or damage to the surrounding hardware.
