Track Washers were developed specifically to secure railroad track assemblies and withstand the intense shock and vibration produced by passing trains. Various styles meet and exceed the specifications of the American Railroad Engineering Association (AREA) and their hold­ing power has been tested and proven “on the job” for over 70 years.

The popular Square Section washer requires up to 4800 pounds of pressure to close. Double Coil Track Washers provide twice the reactive spring range as con­ventional single coil washers.

Track Washers are also used to secure assemblies in structural applications and in car building and rebuilding.
