High Tensile Strength Railroad Track Bolts and Nuts Fish bolt used for rail joints

Fish bolt

A track bolt is used in railway construction as the means of securing the track’s rails to the surface they are applied to. In most cases, when a new rail system is built, the anchors for the track are made of concrete as opposed to the wood that they were traditionally made from. In order to secure the track to the concrete anchors, the track must be anchored into the concrete through the use of a mounting bracket that holds the track’s rail in place. Before the rail can be applied to the mounting bracket, the mounting bracket has to be anchored to the concrete. This is done through the use of a special track bolt.

Fish bolt Features

1. Fish bolt have to undergo shear due to heavy transverse stresses;
2. The Length depends on the type of fishplate used, the diameter depend on the hole size of the fishplate;
3. The fish bolts will get loose by the traffic variations and require tightening from time to time
