Railway screw spikes with two ends, fixes the rail together with the clip system. This types of screw spikes are widely used in Africa. We use special material TD16 to produce the railway screw spike to meet the bending test, bending 30 degree and straightening it, without crack.
The double-head screw consists of two threaded ends and a rigid middle shank, capable of withstanding impact and vibration from train operations. The head can be square or hexagonal for installation with wrenches or specialized tools.
