The M22×70 Track Bolts and Nuts are heavy-duty fastening components designed for excavator and bulldozer undercarriage systems. Engineered to secure track shoes and crawler assemblies, they provide exceptional fastening strength under continuous vibration, heavy impact, and demanding jobsite conditions.
Reliable fastening is essential to the safety and efficiency of crawler machinery. Track bolts and nuts must withstand continuous stress generated by heavy loads, uneven terrain, and repeated operating cycles. The M22×70 track fastener set is designed to maintain secure clamping force while minimizing loosening, helping reduce maintenance costs and improve equipment uptime.
Suitable for construction contractors, mining operators, machinery dealers, equipment manufacturers, and maintenance service providers, these fasteners provide dependable performance in demanding applications.
Manufactured from premium alloy steel using precision hot forging, CNC machining, and controlled heat treatment, these fasteners offer superior mechanical performance, excellent wear resistance, and dependable durability for OEM assembly and aftermarket replacement.
Forged alloy steel construction provides excellent tensile strength and impact resistance for heavy-duty crawler applications.
Precision thread machining helps maintain stable preload, ensuring secure fastening even under severe vibration and dynamic loads.
Heat-treated threads and contact surfaces resist abrasion, extending service life in high-friction operating environments.
Optimized manufacturing reduces the effects of repeated stress cycles, helping prevent premature fastener failure.
A durable surface treatment protects against moisture, mud, oxidation, and harsh outdoor conditions.
Manufactured with tight dimensional tolerances to ensure smooth installation and compatibility with standard undercarriage assemblies.
Choosing our M22×70 track bolts and nuts helps customers achieve:
Every M22×70 track fastener is produced using advanced manufacturing technology and strict quality control procedures.
Certified alloy steel is selected to provide excellent strength, toughness, and durability.
The forging process improves grain flow, increasing structural integrity and impact resistance.
Automated machining ensures accurate thread geometry and dimensional consistency.
Controlled quenching and tempering optimize hardness while maintaining sufficient toughness for heavy-duty applications.
Protective coatings improve corrosion resistance and enhance long-term reliability.
Each production batch undergoes rigorous testing, including:
They are designed to secure track shoes to crawler track links, providing reliable fastening for excavators, bulldozers, and other tracked equipment.
Forged alloy steel offers higher tensile strength, improved fatigue resistance, and greater durability than standard steel, making it ideal for demanding undercarriage applications.
