The Honda 90102-YG0-003 Bolt-Washer (10X30) is a genuine OEM fastener designed for Honda WT20, WT30, and WT40 water pumps. As a direct Honda OEM component, this bolt-washer is manufactured to the exact specifications required for these pumps, ensuring a correct fit without guesswork.

Keep a spare on hand — having the right hardware available means your pump stays in service when it matters most.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this bolt-washer carries the correct dimensions and thread specification for WT-series water pump applications, eliminating the risk of mismatched fasteners
- Integrated Washer Design — the captive washer face distributes clamping load evenly across the mating surface, reducing the chance of loosening under the vibration and load cycles typical of pump operation
- WT-Series Pump Fitment — listed for Honda WT20, WT30, and WT40 water pumps; verify your unit's serial number against the fitment table to confirm the correct part for your specific pump
A bolt-washer is a fastener that combines a threaded bolt shank with an integrated washer flange at the head. In a water pump assembly, fasteners like this one secure components that must stay firmly in place during continuous operation — vibration and hydraulic forces place constant stress on every joint in the pump. A fastener that is the wrong size or has a worn thread can work loose over time, leading to leaks, misalignment, or component damage that takes a pump out of service. Using the correct OEM hardware means the joint performs as Honda engineered it to.
