Function of track bolt
A track bolt is a crucial component in railway construction, used to fasten tracks securely in place. Typically, when installing new rails or connecting existing ones, track bolts are tightened to ensure proper alignment and stability.
Comprising more than just a threaded bolt, a typical track bolt assembly includes several fasteners: a threaded bolt, a nut, and sometimes a lock washer. The lock washer serves to prevent the track bolt from loosening due to the intense vibrations generated by passing trains. By engaging with the bolt, the lock washer helps prevent slippage or twisting, ensuring the bolt remains securely in place. This method is widely employed in rail fastening systems.
To meet the stringent requirements of rail fastening systems, track bolts must exhibit maximum strength to resist any potential shifting. Therefore, they are typically constructed from hardened steel, specially treated to prevent rusting and maintain durability. Regardless of whether the tracks are constructed from concrete, wood, or other materials, track bolts must meet the diverse design requirements of various railway configurations.
