    Types of railroad spikes:


    At before, the screw spikes are usually used to fasten the ribbed base plates and sole plates to wood sleepers. With the construction and development of the concrete sleepers, the screw spikes play an important role in railway fastening systems with the help of a plastic dowel. In order to meet the different use and standards of railway tracks, the screw spikes can be classified into so many types. Now all railroad spikes are made out of carbon steels. Through the different specific geographic requirements such as lengths, diameters, drive heads and thread profiles, the railway screw spikes can be classified into four types: Ss series sleeper screw, square head screw spike, hexagon screw spike and double-head screw spike.
