16×120 Track Roller Bolts Manufacturer

16×120 track roller bolt is a core fastener in excavator and bulldozer track undercarriage systems, bearing severe impacts and continuous shear forces. Under heavy-duty excavation and severe operating conditions, the physical performance of undercarriage fasteners directly determines the overall operation stability and operating safety of the equipment. The 16×120 track roller bolt is specifically developed for high-frequency impact and heavy-load conditions, significantly reducing abnormal wear rates during daily operation and maintenance.

• High-strength mechanical performance: Manufactured with grade 12.9 high-strength alloy steel, with tensile strength exceeding 1200 MPa, paired with an optimized thread-locking structure to significantly reduce the risk of loosening and breakage under high-intensity operations.
• Corrosion-resistant coating technology: Offers multiple surface treatment choices. Among them, Dacromet treatment achieves stable neutral salt spray testing exceeding 96 hours, while phosphate blackening is suitable for conventional humid conditions, effectively lowering rust rates.
• Broad brand compatibility: Precisely matches undercarriages of major brands including Komatsu, Hitachi, Caterpillar, Volvo, Kobelco, Daewoo, Doosan, Hyundai, Kubota, Bobcat, Yanmar, SANY, Liugong, XCMG, and Shantui.

By introducing strict manufacturing standards and high-standard surface anti-corrosion solutions, this specification bolt effectively extends the fatigue resistance life of track rollers in mud, water, and humid environments, providing long-term reliable fastening guarantees for engineering construction.
