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.
