The Honda 90004-Z1L-000 Flange Bolt (6X80) is a genuine OEM fastener designed for the GCV160 vertical shaft engine. Sourced directly from Honda, this bolt carries the exact dimensions and thread specification Honda engineers specified for this application. Confirm your engine's serial number against the fitment table to ensure part number 90004-Z1L-000 is the correct bolt for your serial range before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, so dimensions, thread pitch, and flange geometry match what was installed at the factory on GCV160 vertical shaft engines.
- Integrated Flange Design — the built-in flange spreads clamping load across a wider bearing surface, reducing the risk of fastener loosening under engine vibration without the need for a separate washer.
- Serial-Range Awareness — Honda supersedes fasteners at production breaks; verify your GCV160 serial number against the compatibility table to confirm this is the correct bolt for your unit.
A flange bolt combines a standard hex bolt with an integral wide-diameter flange beneath the head. The flange acts as a built-in washer, distributing clamping force over a broader contact area and helping the fastener hold its torque setting even under the steady vibration an engine produces during operation. When a flange bolt of the correct length and thread specification is missing or replaced with a non-matching fastener, components can work loose over time, leading to misalignment, oil or coolant leaks, or structural failure at the joint it secures.
