The main purpose of wheel bolts is to fix the vehicle wheels to the vehicle hubs to ensure that the wheels maintain a safe and stable connection during driving. Specifically, wheel bolt uses include:

Securely connects wheels and hubs: Wheel bolts provide a safe driving environment by securing the wheels to the vehicle's hubs, ensuring that the wheels do not loosen or fall off while driving.

Transmitting the load of the vehicle: The wheel bolts not only have to bear the weight of the vehicle itself, but also need to withstand various loads and impacts caused by the road surface and driving conditions when the vehicle is driving.

Maintain wheel position and balance: Wheel bolts secure the wheel to the wheel hub, helping to maintain the correct position and balance of the wheel, ensuring stability and comfort when driving.

Accommodates Different Vehicles and Tire Designs: Different types of vehicles and tires may require different sizes and types of wheel bolts to accommodate various vehicles and driving conditions.

Affects the vehicle's handling and driving performance: The tightness and quality of the wheel bolts will affect the vehicle's handling performance and driving safety, so it is important to install and maintain the wheel bolts correctly.

In general, wheel bolts are an important part of the vehicle and are directly related to the safety, driving stability and driving experience of the vehicle. Therefore, they need to be inspected and maintained regularly to ensure that they are in good working condition.
