↵Rail Screw Spike Fastening System
Railway Screw Spike is a heavy-duty threaded fastening component specially designed for modern railway systems, used to securely fix rail fastening assemblies, tie plates and rails to concrete sleepers. It offers high pull-out resistance, strong anti-loosening performance and stable clamping force under long-term dynamic loads, effectively controlling rail displacement, ensuring structural stability and safe operation for high-speed railways, heavy-haul lines, urban transit and various ballastless track systems.
