The screw spike is also known as rail screw. As one kind of Rail spike, it is a metal screw for fixing rail fasteners. Screw spike is usually made of NO.3 steel. 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.
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.

The Tie Plate employ spring compression to hold tie plates firmly in place on cross ties and bridge timbers. They can be driven with standard track tools. Spikes are placed on the diagonally opposite hold-down holes of the tie plate and driven in prebored holes in the tie. Holes of 9/16 in. diameter are drilled to a depth of 7 in. below the top of the tie plate. Spikes are available in 6 in. or 7 in. lengths.Two lock spikes normally are used in conjunction with two standard cut spikes in each tie plate.
