Washer Based Head Hexagon Bolt

About this product

The Washer Based Head Hexagon Bolt (#90105-10247), a critical Engine-Fuel component in the Water Pump system of Toyota vehicles, primarily secures and tightens other parts within the engine. This bolt functions by using a hexagonal upper head for tightening and a built-in washer to distribute load evenly, thus preventing any potential leaks in the system. Over time, this bolt may corrode or wear down, thus losing its ability to maintain a tight seal. When this occurs, it can lead to leaks within the system, potentially causing serious damage to the engine. Hence, periodic replacement with genuine parts, which are backed by Toyota's genuine parts warranty, is essential. By maintaining a secure seal and preventing leaks, the Washer Based Head Hexagon Bolt (#90105-10247) contributes significantly to the overall efficiency and safety of the vehicle's Water Pump system.
