Hexagon head railway sleeper screws are high-strength fasteners widely used in railway fastening systems to secure rails to wooden or concrete sleepers, ensuring track stability and safety. Depending on the application and load requirements, different steel grades can be selected to balance strength, toughness, and cost efficiency.
Q235 steel is a common carbon structural steel known for its good plasticity and weldability, with tensile strength ranging from 375–500 MPa. It is suitable for light railways, subways, or general transport track systems where the impact load is relatively low.
35# steel is a medium carbon steel with higher strength and toughness, offering a tensile strength of around 610 MPa. It is widely used in standard railway and industrial rail systems. This grade provides a good balance between mechanical performance and cost, making it one of the most commonly used materials for sleeper screws.
45# steel is a high-strength medium carbon steel with excellent mechanical properties and wear resistance, featuring a tensile strength exceeding 740 MPa. After heat treatment, its hardness and fatigue resistance are greatly enhanced, making it ideal for heavy-duty railway, mining transport rails, and high-stress fastening systems.
