The screw spikes are also called rail nail screw. Screw spikes are a type of spikes, which are metal screws used to fix railway fasteners. Screw spikes are usually made of No. 3 steel. Due to the inconvenience of disassembly and assembly, it is difficult to adjust the rail gauge, so it is generally used on railway turnouts.
