Brief Introduction

A rail joint bolt is used in railway construction as the means of securing the tracks 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 tracks 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.
