Track Bolt

 



A track bolt is commonly used in railway construction as a mean of fastening the track it is applied to. In most cases, when a new rail is built, in order to secure a track or connect two rails, it must be tightened through the use of a track bolt that holds the track's rail in right place. The track bolt itself is consisted of more than just a threaded bolt. It usually includes two or three-part of fasteners which are a threaded bolt, a nut and sometimes a lock washer. The washer can prevent the track bolt from shifting or getting loose through the intense vibrations caused by a passing train. Once the lock washer can engage the bolt, the bolt is then kept from slipping or twisting loose. This is the most common method for fastening a rail track for the rail fastening system.

Due to the needs of the fastening system, it has to be as strong as possible to prevent any possibility of shifting. As a result, most of the track bolts are made out of hardened steel. The steel is specially treated for preventing it from becoming easy to be rusty. Regardless whether the tracks are made out of concrete, wood, or any other material, a track bolt shall be met with the requirements of different designs of railways.
