The Rail screw spikes pull-out resistance is 0.5 ~ 1.0 times larger than that of common rail dog 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.

As for the cost, the rail screw spike require higher cost than the rail dog spike but has the advantage of greater fixing power; approximately twice that of a rail spike, and can be used in combination with spring washers.
