The Honda 16024-Z0A-004 Drain Screw Set is a genuine OEM component designed for GCV520, GCV530, GXV520, and GXV530 vertical shaft engines. As a factory-original part, it delivers the exact fit and function Honda specifies for these engines, with no guesswork on sizing or thread compatibility. Sourced directly from Honda, this set is the straightforward choice when servicing or rebuilding the fuel system on these vertical shaft engines.
Key Features
- Genuine OEM Fuel System Fit — factory-original Honda components engineered to the exact thread pitch and seating geometry the carburetor drain requires, so the seal holds and fuel drains fully without weeping.
- Covers Four Engine Families — fits GCV520, GCV530, GXV520, and GXV530 vertical shaft engines; verify your engine's serial number against the fitment table, as Honda supersedes parts at serial breaks.
- Service-Ready Set — supplied as a complete set so both the screw and any accompanying components are replaced together, maintaining consistent sealing performance after every drain service.
A carburetor drain screw gives a technician a controlled way to empty the float bowl of fuel before storage or carburetor service — without disconnecting fuel lines or removing the carburetor from the engine. On vertical shaft engines like the GCV520, GCV530, GXV520, and GXV530, where the carburetor sits in a tight engine bay, a reliable drain point simplifies routine maintenance considerably. When the drain screw threads are worn or the seating surface is damaged, fuel can seep past the closed screw, creating a hazard and contaminating the area around the carburetor; replacing the full set restores a clean, positive shutoff.
