Customized Screw Spike

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.For meeting various needs of clients, we can offer coach screws, stud screw, railway sleeper screws and other coustom screw spike in railway.

Rail screw spike Fastening System

Railway Screw Spikes are helical-threaded fasteners engineered for high-retention rail securing, featuring a tapered point with continuous spiral threads and a forged head with drive socket. These precision components transform rotational force into axial clamping tension, embedding threads into timber fibers or engaging with cast-in dowels in concrete sleepers to deliver up to 40kN pull-out resistance while permitting controlled removal for maintenance cycles.
