Plain Oiled 23×174mm Double Head Screw Spike

The Double Head Screw Spike is a commonly used fastener for securing rails to sleepers, designed in compliance with the NF F500-15 international standard. Manufactured from high-strength carbon or alloy steel, it is precision-threaded and oil-coated for enhanced protection against corrosion. GNEE RAIL's Plain Oiled Double Head Screw Spike provides reliable anti-rust and anti-moisture performance, making it suitable for standard railway lines, light rail systems, and dry climate environments.

Double-head screw spikes have two threaded ends, one end used in railway tracks and another end used in sleepers. This helps to provide extra fixed force and stability. They are always widely used in concrete sleepers, especially the situations needing higher fixed force and structural stability, such as heavy haul rails and high-speed rails.

If you have special requirements for dimensions or higher strength materials, please contact us for special custom production.

Surface treatments for railway screw spikes primarily focus on corrosion protection and aesthetic finish, including galvanizing (both hot-dip and electroplating), dacromet coating, oxide blackening, and various paints or oils. Other protective measures involve applying specialized anti-corrosion grease to the spikes to enhance durability against vibration and environmental factors.

The main difference is that a Double Head Screw Spike has two screw heads on opposite ends, while a Square Head Screw Spike has a single, square-shaped head at one end. The double-head version is specifically designed for certain systems like the Nabla clip fastening system and is common in Africa, while the square head screw spike is a more standard type used for fastening railway rails to sleepers in various regions.

Square Head Screw Spike

Just as its name, the square-head screw spike has one square head and another end is the thread. Under most circumstances, although they are suitable for occasions requiring high fixed force, they still mainly apply to traditional wooden sleepers and do not fit concrete sleepers.
