Products Detail

Track bolts, mainly including BHON button head oval neck track bolts and BHDN button head diamond neck track bolts, are professional high-strength special fasteners specially developed for railway track fixation and heavy-duty infrastructure connection scenarios. The two core types share identical mechanical performance and assembly functions, with the only difference lying in the neck profile design to adapt to different track base mounting requirements. Engineered for extreme stability and long-term fatigue resistance, these track bolts serve as critical fastening components for securing rails to track substrates, delivering exceptional shear resistance, tensile stability and vibration resistance under long-term train impact, dynamic load and outdoor harsh environmental conditions.
Our track bolts are available in multiple strength grades including Grade 2, 5, 8 and B7, manufactured from carbon steel and alloy steel materials to meet diverse load-bearing and durability requirements of railway and engineering projects. The product size range fully covers imperial specifications from 3/8” to 2” , adapting to various standard track assembly models. Adhering to strict professional production processes, all BHON track bolts undergo standardized heat treatment before thread rolling, which optimizes internal metal structure, eliminates material stress and ensures uniform mechanical properties. BHON track bolts are universally matched with heavy square nuts and heavy hex nuts to form complete track fastening assemblies.
With excellent structural stability, wear resistance and weather resistance, our track bolts are not only widely applied in railway track laying and track fixation projects, but also suitable for bridge engineering, chemical pipeline fastening and other heavy-duty industrial connection scenarios. To meet diverse customer delivery and storage demands, we support multiple mature packaging solutions, including 200lb metal kegs, 50lb metal pails, 50lb plastic pails, wooden cases and pallet boxes, and fully support customized packaging according to customer requirements.
