The Honda 16024-ZN1-003 Drain Screw Set is a genuine OEM component designed for GX670 horizontal shaft engines and GXV670 vertical shaft engines. As a direct Honda OEM part, this set is manufactured to the same specifications as the original hardware installed at the factory. This Drain Screw Set is the correct service part for GX670 and GXV670 engines, and buyers should confirm their engine's serial number against the fitment table to ensure this is the right set for their specific unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring the correct thread form, dimensions, and sealing function for the drain application on GX670 and GXV670 engines
- Complete Set — supplied as a matched set so all drain screw components are replaced together, maintaining a consistent seal
- Broad 670 Engine Coverage — fits both the GX670 horizontal shaft engine and the GXV670 vertical shaft engine; confirm your model and serial number before ordering
- Fuel System Integrity — a properly seated drain screw prevents fuel leaks at the bowl, keeping the carburetor ready to deliver consistent fuel flow to the engine
A drain screw set is the hardware used to seal the fuel bowl drain on the carburetor, allowing controlled draining of fuel during service or storage. When the screw or its sealing components wear, crack, or strip, fuel can seep from the bowl, causing a lean condition, a fuel odor, or a fire hazard. Replacing the full set at service intervals — rather than the screw alone — ensures a complete, leak-free seal and restores the carburetor's ability to hold and meter fuel correctly.
