The Honda 90108-YG2-003 Bolt-Washer (12X35) is a genuine OEM fastener designed for the WT40 water pump. As a direct Honda OEM component, this bolt-washer is manufactured to the same specifications as the original hardware installed at the factory. Confirm your pump's serial number against the fitment table before ordering to ensure this is the correct fastener for your specific unit.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, so the thread form, shank length, and integrated washer bearing surface match the original fastener exactly.
- Correct 12X35 Specification — the 12 mm diameter and 35 mm length are specific to this application; substituting an incorrect size risks improper clamping and fastener failure.
- WT40 Fitment — listed for the Honda WT40 water pump; verify your serial number against the compatibility table to confirm this is the right part for your unit.
A bolt-washer is a combined fastener that integrates a bolt and a bearing washer into a single piece, distributing clamping load evenly across the mating surface and reducing the risk of loosening under vibration. On a high-flow pump like the WT40, fasteners are subject to sustained engine vibration and hydraulic stress, making the correct hardware critical to keeping assembled components secure. Using an undersized or incorrect fastener can lead to uneven clamping, fretting, or fastener pull-through over time.
