Ss35 Sleeper Screw Grade 4.6,5.6 And 8.8 To UIC864-1 24x161mm
Oct 23, 2025
Ss35 sleeper screws are key fasteners in railway track fastening systems, specifically designed to securely attach rails to sleepers, ensuring gauge and track structure stability. The 24x161mm screws are suitable for different grades of railway lines, with grades 4.6, 5.6, and 8.8 representing different tensile strength, yield strength, and load-bearing capacities, allowing selection according to railway type and load requirements.
Made from high-quality steel, these threaded screws provide excellent holding and pull-out resistance, effectively resisting longitudinal and lateral vibrations from train operations, reducing track loosening and wear, and extending track service life. Grade 8.8 screws are suitable for heavy-duty and high-speed rail lines, while grade 4.6 is ideal for standard lines, meeting diverse construction requirements.
Ss35 screws can be used in combination with rail pads, tie plates, and sleeper bolts to form a complete track fastening system. The threaded design ensures precise rail positioning, cushions train impacts, and enhances track durability and stability.
