As an intermediate connecting component between the rail and the sleeper, the rail fastening system plays a critical role in securing the rail to the sleeper, maintaining track gauge, and preventing both longitudinal and lateral displacement of the rail relative to the sleeper. The screw spike is a key part of the fastening system and is one of the most commonly used components in railway track infrastructure.

Railway spikes, as the core connectors in the track fastening system, secure the rails, sleepers (or track slabs), and fastener components like spring clips and pads. Through threaded engagement or mechanical anchoring, they transmit the longitudinal impact, lateral thrust, and vertical loads generated by train movement, preventing rail displacement, overturning, or gauge widening. GNEE RAILWAY RAILWAY offers a variety of spiral spike types, including the Ss series Sleeper Screw, Square head screw spike, Hexagon screw spike, and Double head screw spike. These spikes are manufactured in strict accordance with international standards to ensure maximum effectiveness.
To ensure the safe operation of trains, the fastening system must exert sufficient clamping force on the rails. The integrity and performance of screw spikes are vital to the effectiveness of the entire rail fastening system.
Maintaining the proper condition of screw spikes involves two main aspects:
- Ensuring the quality of the screw spikes meets required standards.
- Using correct anchoring and installation methods during construction.
One common anchoring method involves embedding the screw spike directly into the sleeper after pouring a sulfur-based anchoring compound, waiting for it to solidify. While convenient, this method:
Is highly dependent on the operator's skill.
A slight hand movement can cause the spike to tilt.
If the spike is installed at an excessive angle, it can increase the difficulty of future track maintenance.
Additionally, excess anchoring compound that overflows and solidifies is difficult to clean.
However, by using a screw spike positioning jig (screw spike locator), the installation process becomes significantly more efficient, accurate, and consistent.
The installation of screw spikes must comply with strict technical specifications-including precise installation height and position. The screw spike positioning jig is a specialized tool designed based on the sleeper geometry, used to accurately guide and position screw spikes during the anchoring process.Different types of sleepers require matching models of screw spike positioning jigs to ensure compatibility and proper alignment during track construction.
