Products Description
Round Head Railway Track Fishplate Bolts are essential components in railway infrastructure, specifically designed to secure fishplates (joint bars) that connect adjacent railway tracks. These bolts feature a round head for easy installation and are manufactured from high-strength steel to withstand the dynamic loads and vibrations experienced in railway operations.
Key Specifications:
Material: High-strength steel (typically Grade 8.8 or Grade 10.9)
Sizes Available: Common sizes include M16, M20, and M22 (metric)
Head Type: Round Head
Thread Type: Metric Fine (MF) or Unified National Coarse (UNC)
Surface Finish: Plain or Zinc Plated for corrosion resistance
Products Process
The production of Round Head Railway Track Fishplate Bolts begins with the selection of quality steel rods. These rods are cut to length and then undergo forging or hot heading to form the bolt heads and bodies. Heat treatment follows to achieve the required mechanical properties such as hardness and tensile strength. Threads are then rolled or machined onto the bolts, ensuring precision and durability. Each bolt undergoes strict quality control measures to meet railway industry standards for reliability and safety.
Products Application
Railway Infrastructure: Used to secure fishplates (joint bars) that connect and align adjacent railway tracks.
High-Speed Rail: Essential for maintaining track integrity and safety in high-speed railway systems.
Heavy Freight Rail: Ensures reliable track connections under heavy loads and frequent vibrations.
Urban Transit Systems: Vital for maintaining smooth and safe railway operations in metro and light rail networks.
