The Honda 90203-ZG5-003 Hexagon Nut (10MM) is a genuine OEM component designed for the EB12 generator. Sourced directly from Honda, this nut matches the exact specifications Honda used when the EB12 was built, ensuring a proper fit the first time. If you're restoring or servicing an EB12 generator, verifying the part number 90203-ZG5-003 against your machine's parts list before ordering is always a good practice.

Key Features

  • Genuine Honda OEM — sourced directly from Honda, matching the original specification used on the EB12 generator at the time of manufacture.
  • Correct 10MM Thread — the 10MM sizing is specific to the fastening point this nut is catalogued for; confirm your application before ordering.
  • EB12 Generator Fitment — listed for the Honda EB12 generator; check your unit's serial number against the fitment table to confirm this is the right hardware for your serial range.

A hexagon nut is a standard six-sided fastener used throughout Honda generator assemblies to secure components firmly in place. The correct nut size and thread pitch matter because an incorrect fastener can strip threads or fail to hold adequate clamping force, leading to loose components during operation. Using the genuine Honda replacement ensures the thread engagement.
