Product Introduction

The AZ9112340123-1 rear wheel nut is a heavy-duty fastening component used in SINOTRUK HOWO rear axle wheel hub assemblies. It is designed to securely fasten the wheel and hub structure to the axle system, ensuring stable wheel retention and safe vehicle operation under heavy load conditions.

Manufactured from high-strength alloy steel and processed through heat treatment technology, this wheel nut provides excellent tensile strength, fatigue resistance, and anti-loosening performance during continuous heavy-duty operation. The hardened surface improves wear resistance and extends service life under high torque conditions. Similar HOWO rear wheel bolt and nut systems are widely used in HOWO heavy truck axle assemblies.

This component works together with wheel bolts, hub assemblies, brake drums, and axle systems to maintain wheel stability during long-distance transportation, mining operations, and construction applications.

The AZ9112340123-1 rear wheel nut is commonly used in HOWO 371, HOWO A7, and other SINOTRUK heavy-duty truck platforms equipped with rear drive axle systems. OEM-standard precision manufacturing ensures accurate thread matching and reliable installation performance.

Each unit undergoes strict quality inspections including hardness testing, thread precision inspection, torque resistance verification, and fatigue durability testing before shipment.
