Track plate bolts are high-strength fasteners specifically designed for excavators, loaders, bulldozers, and mining track type construction machinery. They are mainly used to lock and fix track plates to support wheels, track frames, and chain rail joints, and can withstand long-term walking impacts, sand and gravel friction, soil immersion, and continuous vibration. They are key load-bearing components of chassis walking systems. The products are divided into standard track bolts, extended track bolts, raised flange track bolts, anti loosening track bolts and other models, suitable for various engineering mining track equipment, and are supplied in complete sets with special nuts and flat pads. The raw material used is 40Cr and 42CrMo alloy structural steel, which is formed by cold heading head, CNC precision turning rod body, and high-precision wire rolling processing. After overall quenching and tempering heat treatment, the strength can reach 10.9 and 12.9 levels, balancing high tensile strength and impact toughness. It is not easy to elongate, fracture, or slide under heavy load walking conditions in gravel, hard soil, and mining. The bolt head is designed with thickened and widened flanges, which provides a larger force bearing area and is less likely to crush the track shoes; The thread profile is full and regular, combined with an anti loosening structure, making it difficult to loosen on its own during long-term bumpy operations. The surface adopts multiple protective processes such as high-temperature blackening, phosphating, electroplating zinc, and Dacromet. The coating is dense and wear-resistant, which can resist mud erosion, rainwater corrosion, and mud corrosion, and avoid thread rust and difficult disassembly after long-term use. The finished product has undergone hardness testing, tensile load testing, impact fatigue testing, and full inspection of thread gauges, with standardized dimensions, strong interchangeability, and high assembly fit. Compared with ordinary standard bolts, track plate bolts are optimized for their load-bearing structure, significantly improving their resistance to vibration and wear, effectively reducing downtime losses caused by frequent maintenance and replacement of parts on construction sites. Widely compatible with small excavators, medium-sized engineering equipment, large mining bulldozers, loaders and other tracked models, covering scenarios such as earthwork infrastructure, open-pit mines, sand and gravel mining, tunnel construction, demolition projects, etc. Regular standard specifications are readily available in stock, supporting customized extension, thickening, and special pitch non-standard track plate bolts based on track models and drawings.
