The Honda 16028-ZK7-S91 Screw Set is a genuine OEM component designed for an extensive range of Honda generators, tillers, horizontal and vertical shaft engines, lawn mowers, snow blowers, riding mowers, water pumps, and power carriers. As a factory-original part, this Screw Set is manufactured to the same standards as the hardware installed at the time of production, ensuring correct thread form, torque retention, and dimensional accuracy for the application. This part covers a broad cross-section of Honda equipment, so confirm your model and serial number against the fitment table before ordering to ensure you receive the correct set for your unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this Screw Set carries the correct thread specification and head geometry for the application, so it seats and torques properly without the risk of cross-threading or under-clamping that mismatched fasteners can cause.
- Direct OEM Replacement — engineered to drop in where the original hardware was removed, this set installs without rework or modification to the surrounding components.
- Broad Honda Compatibility — fits a wide range of Honda generators, tillers, horizontal and vertical shaft engines, lawn mowers, snow blowers, water pumps, and more, including GX160, GX390, GCV160, GXV160, and many others listed in the fitment table.
- Serial Number Verification Recommended — Honda updates and supersedes fastener sets at production breaks, so check the serial number on your machine against the fitment table to confirm part number 16028-ZK7-S91 is correct for your specific unit.
A screw set supplies the fasteners that secure carburetor components — typically mixture screws, pilot screws, or related hardware — keeping fuel metering circuits closed and properly adjusted during operation. When these screws are damaged, stripped, or lost, the carburetor can no longer hold a consistent fuel-air mixture setting, leading to rough idle, hard starting, or poor throttle response. Installing a correctly matched set restores the carburetor's ability to maintain its adjustment and return the engine or equipment to normal running condition.
