The Honda 90201-Z0A-000 Flange Nut (8MM) is a genuine OEM fastener designed for GCV520, GCV530, GXV520, and GXV530 vertical shaft engines. As a direct Honda OEM part, it meets the exact specifications used in original assembly, ensuring a correct, secure fit with no guesswork. This flange nut is listed for the GCV520, GCV530, GXV520, and GXV530 — verify your engine's serial number against the fitment table to confirm the right application before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this nut matches the original thread pitch, flange diameter, and torque specification used during factory assembly of these vertical shaft engines.
- Broad Vertical Shaft Engine Coverage — listed for GCV520, GCV530, GXV520, and GXV530 engines; check your serial number against the fitment table to confirm the correct application for your unit.
- Flange Design for Secure Clamping — the integrated flange distributes clamping load across a wider bearing surface compared to a standard hex nut, helping to maintain fastener tension under engine vibration.
- Serial Number Verification Recommended — Honda supersedes hardware at serial number breaks, so always cross-reference your engine serial number with the compatibility table to ensure this is the current specification for your engine.
A flange nut combines a standard hex nut with a wide, washer-like base in a single piece, spreading the clamping force over a larger contact area than a plain nut alone. This helps maintain consistent fastening tension on assemblies subject to the vibration and thermal cycling that vertical shaft engines routinely experience. When a flange nut loosens or is replaced with an incorrect fastener, it can allow the components it secures to shift, potentially leading to misalignment or premature wear of the surrounding assembly.
