Oct 23, 2025
Screw spike is also called sleeper screw, rail screw, through specific requirements such as length, diameter, drive head and thread profiles, the railway screw spikes can be classified into four types, including the Ss series sleeper screw, the square-head screw spike, the hexagon screw spike, and the double-head screw spike.
The NF F500-15 23×174mm double head screw spike is a high-strength critical fastener in railway track fastening systems, specifically designed to secure rails to sleepers and ensure track stability during train operations. Its double-head design provides bi-directional clamping force, creating a tight connection between the rail, sleeper, and tie plate, enhancing pull-out resistance and overall track stability. This screw effectively absorbs longitudinal and lateral vibrations from train operations, reducing track loosening and wear, ensuring long-term safe operation.
