Spike Steel 

There are two types of spike steel: low carbon steel and high carbon steel. Steel is iron added with carbon. Without carbon, steel is too soft and difficult to make good strengthened rail spike. The application of adding carbon to iron makes the steel quickly take the place of cast and wrought iron. Carbon makes the steel hard, but more carbon in spike steel may make it brittle.  Approximately 0.7–2.5% carbon content is high carbon steel. Most rail spikes are made of high carbon steel.  

Types of Railroad Spike

Two common types of rail spike are screw spikes and dog spikes.

Screw Spike

Screw spike is first introduced in France in 1860,and is used to fasten the tie plate or pad to wooden sleepers. With the development of concrete sleeper, screw spike becomes more common in railway fasteners. It is always used with the help of the rail plastic dowel, which is pre-inserted into the concrete sleeper before installing rail fastening system. Screw spike can be classified into many types to meet different standards railway tracks. At present, the main types of screw spikes are Ss series sleeper screw, square-head screw spike, hexagon screw spike, and double-head screw spike. The system of rail spike, rail bolts and rail plastic sleeve is considered as a good connection or linkage of rail track and rail sleeper.
