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.
GNEE RAIL can offer coach screws, stud screw, railway sleeper screws and other coustom screw spike in railway.
