D-Series Wear-Resistant Bolts for Liugong CLG856 Loaders, Lingong LG953 Loaders - High-Strength Wheel Loader Fasteners
D-series bolts are optimized for loader operations, fitting mainstream models like Liugong CLG856 and Lingong LG953. Made of high-strength alloy structural steel, they undergo carburizing to achieve a surface hardness of HRC55-60, significantly enhancing wear resistance and extending service life in wear-prone parts such as buckets and booms. The bolt shank is cold-headed to ensure continuous metal fibers, with shear resistance over 30% higher than ordinary bolts. Threads are coated with anti-loosening glue to prevent loosening during frequent lifting operations, ensuring operational safety. Strictly matching original dimensions, they require no additional processing for installation, suitable for heavy-duty conditions like mines and ports. SGS-certified and compliant with construction machinery safety standards, they are ideal for loader maintenance.
