Key Features
- Genuine Honda OEM — sourced directly from Honda, this bolt-washer meets the same specification as the original fastener installed at the factory.
- Integrated Washer Design — the captive washer distributes clamping load evenly, reducing the risk of fastener loosening under the vibration loads typical of pump operation.
- WT40 Water Pump Fitment — listed for the Honda WT40; check your serial number against the fitment table to confirm this is the correct listing for your unit.
A bolt-washer is a fastener that combines a bolt and a washer in a single captive assembly. On the WT40 water pump, fasteners like this one secure key components and maintain the structural integrity of the pump under continuous operating loads. When a fastener fails, loosens, or strips, it can allow components to shift or leak, disrupting pump performance — replacing it with the correct OEM part restores the secure connection the pump relies on.
