The screw spike is also known as rail screw. As one kind of Rail spike, it is a metal screw for fixing rail fasteners. 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.
The 8.8 grade 45# steel coach screw spike is a high-strength railway fastener widely used in railway track systems to securely attach rails to wooden or concrete sleepers, ensuring stability and safety during train operations. It is made of high-quality 45# medium carbon steel and treated with heat processes such as quenching and tempering to enhance tensile, shear, and fatigue strength.
