AZ9100410104 wheel bolt is a critical fastener spare part for Sinotruk Howo heavy truck wheel hub assembly. It is used together with wheel nuts to fasten wheel rim onto the hub, reliably transferring driving force and bearing huge impact and shear load during heavy-duty running. The wheel bolt is forged from high-strength alloy steel, treated by quenching and tempering, featuring high tensile strength, good toughness and fatigue resistance. The thread is precisely rolled to ensure stable fit with wheel nut and prevent thread loosening under long-distance vibration. Each bolt undergoes strict tensile test, hardness inspection and nondestructive crack detection before delivery, to avoid bolt fracture and wheel falling risk caused by fatigue damage. It is a necessary replacement spare part for wheel hub maintenance. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
