Key Features
- Genuine OEM Fastener — sourced directly from Honda, ensuring the correct thread pitch, shank length, and integrated washer bearing surface that the original assembly requires
- Exact-Match Replacement — part number 90091-ZC2-003 is the Honda-specified bolt-washer for these generators; using the correct fastener maintains proper clamping force at the joint it secures
- Generator-Specific Fitment — listed for Honda EB5000, EG5000, EM5000, and EX4500 generators; check your serial number against the compatibility table to confirm the right variant for your unit
A bolt-washer is a fastener that combines a bolt and an integrated washer in a single piece, distributing clamping load across a broader surface area than a plain bolt alone. On Honda generators, using the correct OEM fastener ensures the joint is held to the torque and bearing-surface requirements Honda engineered into the assembly. A fastener of the wrong length, thread pitch, or washer diameter can result in an improperly secured joint, which may allow loosening under the vibration a generator produces during operation.
