Tire Bolts
Tire bolts are core fasteners connecting automobile wheel hubs and axles, directly related to the safety of vehicle driving, and are key components ensuring the firm combination of tires and the vehicle body.
They are mostly made of high-strength carbon steel or alloy structural steel (such as 35CrMo) of grade 8.8 or above. After quenching and tempering treatment, their tensile strength can reach 800-1000MPa, which can bear radial load, impact force and torque when the vehicle is running. The surface is often galvanized or electrophoretic treated to enhance rust resistance, so as to cope with the erosion of complex road conditions such as rain and mud. -
