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.
GNEE RAIL choose high grade raw materials for rail spike production, in order to satisfying higher quality standards. With better reliability, robustness and effective performance, these products are used in large railway projects.

How to use screw spikes
- Clear Purpose:Spiral rail spikes are mainly used to fix railway steel rails and sleepers, ensuring track stability.
- Preparation Work:Confirm the sleeper has pre-reserved holes or drilled holes, prepare a wrench (e.g., torque wrench), and check that the rail spike is free from damage.
- Alignment:Align the threaded end of the rail spike with the sleeper hole, and fit it to the nail hole of the steel rail fastener.
- Screwing and Securing:Use the wrench to screw the rail spike in clockwise, avoid skewing, and tighten it to the specified torque (to prevent looseness or over-tightening).
- Inspection:Confirm that the rail spike fits tightly with the fastener and sleeper, with no displacement or looseness.
