Long Service Life and High Wear Resistant M22×70 Track Fasteners for Excavator or Bulldozer Track Link Assy

The M22×70 Track Fasteners are engineered to provide dependable fastening performance for excavator and bulldozer track link assemblies. Designed to withstand continuous impact, vibration, and high clamping loads, these fasteners securely connect track shoes to track links while maintaining the structural integrity of the complete undercarriage system. Track link assemblies operate under constant stress caused by heavy loads, rough terrain, and continuous crawler movement. High-quality track fasteners play a vital role in preventing loosening, maintaining proper track alignment, and ensuring stable equipment operation.

Our M22×70 track fasteners are designed to maintain stable clamping force throughout long operating cycles, helping operators improve equipment reliability while minimizing unexpected maintenance. Manufactured from premium alloy steel through precision hot forging, CNC machining, and advanced heat treatment, our M22×70 track fasteners combine high wear resistance, superior tensile strength, and excellent fatigue performance. They are widely used for OEM production, aftermarket replacement, equipment overhaul, and preventive maintenance in construction, mining, quarrying, and earthmoving industries.
