Industry knowledge
The railway screw spikes is a fastener used to firmly fix the rail to the sleeper. Its notable feature is that it has a complete thread on the surface and can be connected to the sleeper by screwing in. Unlike traditional hammer-type spikes, screw spikes provide stronger mechanical locking force through the spiral structure during installation, greatly enhancing the overall stability of the track system.
This type of spike is usually used with nylon sleeves or metal threaded sleeves, which can effectively prevent the screw spikes from loosening or falling off under long-term vibration and heavy loads.
Screw spikes are widely used in concrete sleepers and spring clip fastener systems. They are indispensable components in modern railway lines, especially high-density and high-speed lines. With long service life, low maintenance cost and strong stability, they have gradually replaced the use of traditional straight railway spikes in some areas. Especially in railway sections with complex forces and frequent operation, screw spikes can effectively extend the overall service life of the track structure, reduce sleeper loss and fastener loosening frequency, and improve the safety and operation efficiency of the line.
