The Honda 90003-Z1E-000 Flange Bolt (10X85) is a genuine OEM fastener designed for GXV390 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the exact dimensions and specifications Honda engineers specified for this engine. If you are servicing a GXV390 and need to replace this bolt, verify your engine's serial number against the fitment table to confirm part number 90003-Z1E-000 is correct for your serial range before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt meets the exact dimensional specifications required for proper clamping and torque retention in the GXV390 engine.
- Exact Dimensional Match — the 10 mm diameter and 85 mm length are Honda-specified values; an incorrect bolt length or thread pitch can result in improper clamping or thread damage.
- GXV390 Fitment — listed for GXV390 vertical shaft engines; confirm your serial number against the fitment table, as Honda supersedes hardware at serial breaks.
A flange bolt combines a standard bolt with an integrated flanged washer at the head, distributing clamping load across a wider surface area than a plain bolt alone. This helps maintain consistent clamping pressure on the joint it secures within the GXV390 engine. Using the correct OEM bolt — with the right thread pitch, shank length, and flange diameter — ensures the fastened assembly stays properly torqued and avoids thread damage or joint loosening during engine operation.
