Wholesale Excavator Track Bolts and Nuts 20*57

In the chassis systems of excavators and bulldozers, track bolts and nuts are critical components, determining track stability and overall equipment reliability. GFM’s track bolts and nuts 20*57 are designed for heavy-duty construction environments, providing durable performance support for mining, earthmoving, and infrastructure construction. Whether for routine maintenance or large-scale engineering projects, this product ensures smooth and safe operation of the track system.

• High-strength Material Guarantee: Utilizing carefully selected alloy steel, GFM’s grouser track bolts and nuts possess excellent tensile strength and toughness, capable of withstanding the impact and vibration of excavators or bulldozers under high-load operation.
• Precision Machining and Thread Design: Each bolt and nut is precision-machined, with uniform and tight threads, ensuring smooth installation and secure fastening, reducing the risk of loosening due to vibration.
• Heat Treatment Enhancement: Combining quenching and tempering processes, the hardness and wear resistance of the track bolts and nuts are significantly improved, maintaining reliable performance even during extended construction periods.
• Clear Specifications and Easy Matching: With a model number of 20*57, the bolt diameter, length, and thread standards strictly conform to industry specifications, facilitating quick and easy matching with different machine models and improving spare parts selection efficiency.
• Wide Compatibility: Compatible with excavators and bulldozers from brands such as Komatsu, Hitachi, Caterpillar, Volvo, Kobelco, Daewoo, Doosan, Hyundai, Kubota, Bobcat, Yanmar, Sany, LiuGong, XCMG, and Shantui, covering mainstream equipment models on the market and reducing procurement difficulty.
• Durability and Low Maintenance Requirements: Bolts and nuts undergo surface strengthening treatment to improve wear resistance and corrosion resistance, making them less prone to wear even under long-term high-intensity construction, significantly reducing equipment maintenance frequency.
• Reliable Quality Assurance: GFM provides a quality guarantee of no less than one year or 2000 hours. Each batch of products undergoes rigorous testing to ensure that the performance and safety of grouser track bolts and nuts meet industry standards.
