Our range of track bolts and nuts is available with a wide range of diameters ranging from 1/2-1.1/8 inch, or 12-30mm. The bulldozer and excavator spare part is compatible with the Caterpillar, Komatsu, Hitachi, Daewoo, Hyundai, and other reputed brands.
The undercarriage part is manufactured by cold or hot forging equipment, allowing for good surface finish. Because of the strict heat treatment, it comes with the grade at least 10.9. Also, we can make the track bolt and track nut according to the drawings or samples provided by you. Sprocket bolts and nuts are also available.
Our Advantages and Features
The raw material for our track bolts and nuts are acquired from national famous steel suppliers such as Hangzhou Steel Mill, Shanghai Bashan Steel Mill, and Beijing Shrugging Steel Mill. The steel material provided by these companies is characterized by good mechanical properties as well as stable physical and chemical properties. Thus, this range of undercarriage component features high strength and long lifespan.
2). Manufacturing and Processing
First, we posses the high-precision CNC machining center for excellent mould making, thus providing the heavy equipment part with pretty appearance and accurate size. And second, the blasting process is applied to make the surface bright, clean, uniform, and beautiful but without oxidation layer. The third, we utilize the controlled-atmosphere automatic heat treatment furnace to maintain proper hardness. Additionally, we have four mesh belt furnaces for heat treatment to prevent our track bolts and nuts from surface oxidation.
3). Complete Quality Control System
The strict quality control ranges from raw materials purchasing to machining and to final packing. We own such latest inspection equipment as Magnetic Powder Detector, Material Testing Machine, and Metallographic Microscope. Those processes together the advanced testing machines make sure all our track bolts and nuts have high quality and beautiful appearance.
4). Production Capacity
We are capable of manufacturing 70 to 120 pieces of track bolts for per minute. The utilization of full-automatic cold-forging machine has significantly enhanced our capability in producing more track bolts or nuts of better quality and prettier appearance.
