Products Description
The surface of the railroad screw spikes may have some protrusions or burrs, and some spikes may have more or less weight. Compared with this type of railway spike, another common type of railroad screw spikes can avoid these problems, that is, the machine-made spike. The production process of this type of railway spike is a combination of manual and mechanical production.
The surface of the commonly used machine-made spikes is smooth, and the weight of each spike is not much different. The railway spikes produced in this way can be used in batches better, and there will be no problem of high defective rate like ordinary manual spikes during use.
