The Honda 90107-YG2-003 Bolt-Washer (10X40) is a genuine OEM fastener designed for the WT40 water pump. Sourced directly from Honda, this part carries the correct dimensions and thread specification to replace the original hardware without modification. Confirm your pump's serial number against the fitment table before ordering to ensure this is the right part for your unit.
Key Features
- Genuine OEM Hardware — an exact Honda original, manufactured to the same specification as the fastener that left the factory with your WT40 pump.
- Correct 10X40 Sizing — the integrated washer flange and 10 x 40 mm dimensions match the original fastener precisely, so it seats and torques as intended.
- WT40 Water Pump Fitment — listed for the Honda WT40; verify your pump's serial number against the compatibility table to confirm this bolt-washer is the right match for your specific unit.
A bolt-washer is a fastener with a captive washer flange formed as part of the bolt head, combining the clamping function of a bolt with the load-spreading function of a washer in a single component. On the WT40 water pump, this type of hardware secures pump components with consistent clamping force distributed evenly across the mating surface. Using the correct OEM replacement ensures proper torque retention; a fastener with the wrong dimensions can result in uneven clamping, loose assemblies, or damage to sealing surfaces over time.
