Fast Delivery High Strength Rail Screw Spike Hot-DIP Galvanized

Product Description

Please enter the title here

‌Railway Screw Spikes‌ are core fastening components within the railway track fastening system, used to secure the rail to concrete sleepers or wooden sleepers. Featuring a straight cylindrical shank with standard threads (e.g., M22, M24) and a hexagonal or round head designed for compatibility with specialized wrenches, they function ‌in conjunction with nuts‌ to provide lateral and longitudinal fixation of the rail.
 
Core Functions
·Rail Locking‌
Secures rails by generating preload force through nut tightening, restricting lateral displacement and longitudinal creep to ensure gauge precision.
·Load Transfer‌
Distributes vertical loads and lateral impact forces from train operations to concrete sleepers and ballast beds, mitigating localized stress concentration.
·High Pull-Out Resistance‌
Standard screw spikes withstand ≥100 kN pull-out force; heavy-haul variants exceed 150 kN, ensuring reliability in high-frequency vibration environments.
‌·Adjustability‌
Optimizes fastening system clamping pressure dynamically by adjusting nut torque (typically 80–120 N·m), adapting to diverse track conditions.
