M19×70 Excavator Track Bolts and Nuts, High Tensile Track Fasteners, Anti-Corrosion Anti-Loose Undercarriage Hardware, Heat-Treated Heavy Duty Fittings for Africa Mining, Quarry & Muddy Road Construction Machinery, In Stock Fast Shipment To Lagos, Johannesburg
The M19×70 Replacement Track Bolts and Nuts are designed to provide secure and durable fastening for excavator and bulldozer undercarriage systems. Manufactured for demanding applications, these heavy-duty fasteners ensure reliable attachment between track shoes and track links, helping crawler equipment operate safely under continuous vibration, shock loading, and harsh working environments.
Crawler undercarriage systems rely on high-quality fastening components to maintain structural integrity during operation. Track bolts and nuts are constantly subjected to dynamic loads, impact forces, and abrasive conditions. Reliable fasteners help minimize loosening, reduce maintenance frequency, and improve overall equipment productivity.
Our M19×70 track bolt and nut assemblies are manufactured under strict quality control to meet the performance requirements of construction contractors, mining companies, equipment dealers, and spare parts distributors worldwide. Produced from premium alloy steel through precision hot forging, CNC machining, and advanced heat treatment, these fasteners deliver exceptional tensile strength, outstanding wear resistance, and dependable long-term performance. They are suitable for OEM assembly, replacement maintenance, and aftermarket undercarriage repair.
We specialize in manufacturing undercarriage components for construction and mining machinery, combining advanced forging technology, precision machining, strict quality management, and efficient production capabilities. Every M19×70 track bolt and nut is engineered to provide reliable fastening performance, helping customers maximize equipment uptime and reduce total maintenance costs.
With extensive export experience and flexible manufacturing services, we support equipment manufacturers, parts distributors, rental fleets, and maintenance providers across global markets.
