Do You Really Know Screw Spikes?
1. What a Screw Spike Is
A railroad spike (also called rail spike, railway spike, track spike or railroad tie nail) is one of the crucial rail fasteners used to fix rail tracks to railroad sleepers, playing a key role in railway settings. They usually adopt carbon steel or stainless steel materials, such as Q235 carbon steel, Q345B carbon steel, to ensure high strength and durability.
2. Functions
Great durability and corrosion resistance for long train operations and environmental effects.
The special design evenly spreads pressure from trains to sleepers and ground, reducing damage to rails and support structures.
Through nailed-in sleepers, spikes fix the track position, ensuring the railway system's stability and safety and preventing rail shifts and traffic accidents.
3. Screw Spike vs Dog Spike
There are many types of spikes, including screw spikes and dog spikes. From the appearance point of view, the more prominent difference is that the surface of the screw spike has obvious thread - a shape having a uniform spiral protrusion on a section of the outer surface.
