Hexagonal flange bolts have diverse applications across multiple industries due to their unique design features that offer enhanced stability and resistance to loosening. Here are some of their main uses:
Automotive Industry
Vehicle Assembly
In automotive manufacturing, hexagonal flange bolts are extensively used for assembling various parts of a vehicle. For example, they are used to attach the engine components to the engine block. The flange on the bolt provides a larger bearing surface, which helps distribute the clamping force more evenly, reducing the risk of damage to the relatively soft aluminum engine block material.
They are also crucial for connecting the chassis components such as the suspension system to the vehicle frame. The added stability provided by the flange helps ensure that the suspension components remain securely fastened even under the harsh vibrations and dynamic loads experienced during vehicle operation.
Wheel Mounting
Hexagonal flange bolts are commonly used for mounting vehicle wheels. The flange design not only provides a larger contact area with the wheel hub but also helps prevent the bolts from loosening due to the constant vibrations and rotational forces acting on the wheels. This is essential for maintaining the safety and integrity of the wheel - to - hub connection.
