The Honda 16024-ZH7-A20 Drain Screw Set is a genuine OEM component designed for a wide range of Honda tillers, snow blowers, power carriers, and GXV160 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the same specifications as the hardware installed at the factory, ensuring proper sealing and fitment without modification. This set covers an extensive list of equipment, including F210, F220, F401, F501, FC600, FR600, FR650, FR750, FR800, and FRC800 tillers; HP250 and HP400 power carriers; HS521, HS621 single-stage and HS522, HS622, HS624, HS724, HS828, HS928, HS1132, HS1332, HS1336, HSM1336, HSS724, HSS928, and HSS1332 snow blowers; and the GXV160 engine. Honda supersedes parts across serial breaks, so confirm your unit's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM Quality — manufactured by Honda to match the original drain screw specifications, ensuring a proper seal and preventing fuel or fluid leaks at the drain point.
- Broad Equipment Coverage — a single part number serving GXV160 engines, multiple Honda tiller and snow blower lines, and HP-series power carriers, making it a practical stock item for Honda fleet servicing.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your machine's serial number against the compatibility table to confirm this is the correct set for your unit.
- Leak Prevention — a correctly seated drain screw set maintains a tight closure at the drain passage; a worn, damaged, or missing screw allows fluid to seep, creating a mess and risking fuel or oil loss during operation.
A drain screw set provides the threaded fastener and associated sealing components used to close the drain passage on a carburetor or fuel system, allowing fuel to be retained during operation and drained cleanly during service or storage. Keeping this hardware in good condition is essential to controlled draining — a damaged thread or degraded seal lets fuel escape at unintended times, which complicates routine maintenance and can create a fire hazard. Replacing the drain screw set with a genuine Honda part like part number 16024-ZH7-A20 restores the drain circuit to its original condition and keeps service intervals clean and straightforward.
