The screw spike is also known as rail screw. As one kind of Rail spike, it is a metal screw for fixing rail fasteners. Because its nail rod surface has thread, so it is called screw spike. The pull-out resistance is 0.5 ~ 1.0 times larger than that of common rail spike, but the thrust resistance is 50% less. Due to disassembly and assembly inconvenience, it is difficult to adjust the rail gauge, which is generally used on the railway turnout.The primary application scenarios for screw spikes are in railway track laying and track maintenance.
In new railway construction, engineers select the appropriate type of rail fastening spike according to design specifications. GNEE RAIL supplies various screw spike types, including SS series sleeper screws and square-head screw spikes. For example, screw spikes made from 45# high-quality carbon structural steel are widely used on mainline tracks and heavy-haul railways due to their stable performance and durability.
During railway maintenance, if existing rail screw fasteners are found to be loose or damaged, replacement with the same specification screw spikes is carried out to ensure track safety and stability. In addition to providing standard spike sizes, GNEE RAIL offers custom-manufactured screw spikes. With a complete railway fastener production line, we are able to supply all specifications and types of railway spikes.

Beyond the railway industry, screw spikes are also used in certain industrial equipment installations. For example, the base of some large-scale machinery is fixed with similar threaded spikes to enhance vibration resistance. Nevertheless, the railway sector remains the primary field where screw spikes are applied.
