What Size Are Car Tire Bolts?
1 Answers
The size varies for different vehicles, depending on the specific model. Common socket sizes for tire bolts are 17, 19, 21, and 23. Additional information is as follows: 1. Wheel Hub Bolts: Wheel hub bolts are high-strength bolts that connect the wheels to the vehicle. The connection point is the wheel hub unit bearing. Generally, 10.0-grade bolts are used for compact cars, while 12.9-grade bolts are used for medium and large vehicles. The structure of wheel hub bolts typically includes a knurled key section, a threaded section, and a cap head. 2. T-Head Wheel Hub Bolts: T-head wheel hub bolts are mostly grade 8.8 or higher and are responsible for the high-torque connection between the wheel hub and the axle. 3. Double-End Wheel Hub Bolts: Double-end wheel hub bolts are mostly grade 4.8 or higher and handle the lighter torque connection between the outer wheel hub shell and the tire.
