The M25.4x89mm Track Bolts are suitable for:
Every M25.4x89mm track bolt is produced under a strict manufacturing process:
Mining-grade track bolts are engineered to withstand higher impact loads, prolonged vibration, and abrasive operating conditions. They are manufactured with high-strength alloy steel and advanced heat treatment to provide greater durability and fastening reliability.
Maintaining consistent preload helps keep the track shoe securely attached to the track chain, reducing joint movement, minimizing wear, and improving the overall stability of the undercarriage system.
Depending on the application, black oxide, phosphate coating, zinc plating, or Dacromet coating can be selected to improve corrosion resistance and extend service life in wet, muddy, or chemically aggressive conditions.
