The Honda 90104-Z08-E31 Bolt-Washer (6X15) is a genuine OEM fastener designed for Honda EB10000 and EB11000 generators. As a direct Honda OEM part, this bolt-washer is manufactured to the exact specification Honda calls for in these generators. Confirm your generator's serial number against the fitment table to ensure part number 90104-Z08-E31 is the correct listing for your unit before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, so the thread pitch, shank diameter, and integrated washer geometry match the original hardware exactly.
- Correct 6 x 15 Specification — the 6 mm diameter and 15 mm length are the precise dimensions Honda specifies; substituting an incorrect size risks under- or over-clamping at the fastener location.
- Generator Fitment — listed for EB10000 and EB11000 generators; verify your serial number against the fitment table, as Honda updates hardware specifications at serial breaks.
A bolt-washer is a fastener that combines a bolt and an integrated washer in a single piece. The washer flange distributes clamping load across a wider surface area than a plain bolt head alone, helping to secure the joint without pulling through or concentrating stress on the mating surface. When a bolt-washer loosens, stretches, or is replaced with an incorrect size, clamping force is lost and the components it secures can shift or vibrate loose during generator operation.
