24x161mm Ss25 Sleeper Screw

Rail Screw Spike is a vital fastener used to securely fix rails to sleepers, serving as an indispensable component in railway track structures. Compared with traditional dog spikes, screw spikes provide higher pull-out resistance and more durable fastening performance, effectively absorbing the impact and vibration generated by train operations. This ensures accurate track gauge and extends the overall service life of the railway track. The typical structure of a rail screw spike includes a square or hexagonal head, a cylindrical shank, and a single-start coarse thread, making it suitable for use with wooden, concrete, or composite sleepers. Depending on the application environment, screw spikes can be manufactured in various strength grades and with different surface protection treatments, meeting the requirements of high-speed railways, urban subways, and heavy-haul lines.

The Ss25 Sleeper Screw Spike is one of the most commonly used fasteners in sleeper fastening systems, with a specification of 24×161mm, compliant with UIC864-1 standards, and available in Grade 4.6, 5.6, or 8.8 strength classes. Manufactured from high-strength carbon structural steels such as Q235, 35#, 45#, or 40Cr, it offers excellent mechanical performance and durability. The screw thread is precisely rolled for high accuracy, ensuring tight engagement with the sleeper or plastic dowel, which significantly enhances its pull-out resistance and lateral stability, making it ideal for long-term, heavy-duty railway applications.
