Wheel hub bolts are high-strength bolts used to connect the wheels of a vehicle. The connection position is the hub unit bearing of the wheel! Generally, micro cars use level 10.9, while large and medium-sized vehicles use level 12.9!
The structure of wheel hub bolts is generally composed of spline gears and threaded gears! And a hat! The T-shaped head wheel hub bolts are mostly of grade 8.8 or above, responsible for the high torque connection between the car wheel hub and axle!
Double headed wheel hub bolts are mostly of grade 4.8 or above, responsible for connecting the outer wheel hub shell and tire with relatively light torque.
The main function of tire bolts is to fasten the wheel hub and tire together, ensuring that the tire will not loosen or fall off during driving. Specifically, the tire bolts, with their sturdy material and precise thread design, tightly grip the wheel hub and axle, ensuring that the wheels will not loosen during high-speed rotation and bumpy road conditions, thereby ensuring the stability and safety of the vehicle
In addition, the number and type of tire bolts can also affect their effectiveness. For example, some cars use four bolts to secure the tires, while others use five or more. This mainly depends on factors such as vehicle weight, bolt strength, and wheel hub size. Generally speaking, the heavier the vehicle, the stronger the bolts, and the larger the wheel hub, the more bolts are needed. This can better share the stress and ensure the stability and safety of the tires
