[0002] The main reason that heavy-duty vehicles use knurled bolts is to improve the stability and safety of the connection. The knurled bolt increases the friction coefficient by forming a pattern on the surface of the bolt, thereby improving the torque transmission efficiency, preventing the bolt from slipping during tightening and ensuring the tight connection of the wheel and the vehicle body. This design enables the bolt to more effectively transmit torque, ensuring the tight connection of the wheel and the vehicle body, preventing loosening due to vibration, thereby improving the stability and safety of driving. However, relying solely on the knurls on the surface of the knurled bolt cannot effectively and reliably prevent loosening, and the knurls will wear out during bolt disassembly, thereby reducing the anti-skid effect of the knurls.
