The Honda 90011-Z0A-000 Flange Bolt (16X35) is a genuine OEM fastener designed for GCV520, GCV530, GXV520, and GXV530 vertical shaft engines. As an authentic Honda part, it is manufactured to the same specifications as the original hardware installed at the factory. This bolt is listed for GCV520, GCV530, GXV520, and GXV530 engines — verify your engine's serial number against the fitment table to confirm this is the correct part for your unit.
Key Features
- Genuine OEM Hardware — an authentic Honda replacement that matches the original fastener's dimensions and thread specification exactly, ensuring proper clamping without modification.
- Correct Flange Design — the integrated flange distributes clamping load evenly, eliminating the need for a separate washer and maintaining consistent holding force across the joint.
- Broad Vertical Shaft Fitment — listed for GCV520, GCV530, GXV520, and GXV530 vertical shaft engines; check your serial number against the fitment table to confirm applicability to your specific engine.
A flange bolt combines a standard hex bolt with a wide, integrated flange at the base of the head that acts like a built-in washer. This spreads the clamping load over a larger surface area, reducing the risk of loosening under vibration — a common condition in small engine applications. Using the correct OEM fastener ensures the thread pitch, shank diameter, and flange geometry match the original specification, so joints seat properly and torque values remain accurate during service.
