Description
WG7121340130 rear wheel bolt is a critical fastener spare part for Sinotruk Howo heavy truck rear wheel hub assembly. Matched with wheel nuts, it secures the wheel rim tightly on the rear hub, bears huge shear force and impact load during heavy-load transportation and transmits driving torque. This wheel bolt is forged from high-strength alloy steel, processed by quenching and tempering heat treatment. It has high tensile strength, excellent toughness and good fatigue resistance. The thread adopts precision thread rolling technology, which ensures stable matching with nuts and effectively prevents loosening under long-term vibration. Each bolt undergoes strict tensile test, hardness inspection and non-destructive crack detection before delivery, avoiding safety hazards caused by bolt fatigue fracture. It is an essential replacement spare part for rear 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.
