Track Fasteners M19×70, High Tensile Track Bolts And Nuts, High Temperature & Sand Corrosion Resistant Undercarriage Hardware, Heat Treated Anti-Loose Excavator Track Fittings For Middle East Desert Quarry, Oilfield & Construction Machinery, In Stock Fast Delivery
The M19×70 Replacement Track Fasteners are manufactured to provide secure fastening for crawler undercarriage systems used in excavators and bulldozers. Designed for heavy-duty operating environments, these fasteners ensure reliable connections between track shoes and track links, helping maintain machine stability, reduce maintenance frequency, and improve overall equipment efficiency.
Our M19×70 track fasteners are engineered to deliver consistent fastening performance even under demanding working conditions.
Produced from premium alloy steel with precision forging, CNC machining, and advanced heat treatment, the M19×70 track fastener set delivers outstanding resistance to wear, impact, and fatigue. It is an ideal choice for OEM production, aftermarket replacement, and fleet maintenance.
Reliable track fasteners are essential for maintaining the performance and safety of crawler equipment. Every movement of the undercarriage generates vibration, impact, and tensile stress. A high-quality fastening system helps prevent loosening, reduces component wear, and extends the service life of the complete track assembly.
The hardened surface significantly improves resistance to abrasion caused by continuous contact with dust, gravel, mud, and other harsh materials.
Optimized heat treatment creates an ideal balance between hardness and toughness, extending the operational life of each fastener.
Manufactured from forged alloy steel to withstand high tensile loads and repeated mechanical impact.
Precision threads help maintain reliable clamp force while reducing the possibility of loosening during long working hours.
Designed to tolerate repeated loading cycles without compromising structural integrity.
A durable surface coating minimizes oxidation and rust, making the fasteners suitable for challenging outdoor environments.
