Track Washers have been standardized for the rail industry since 1887.

While that standard predates ITW Shakeproof, our track washers were designed to exceed the ultimate test of any rail- joint spring washer—maintaining proper bolt tension under extreme shock, vibration, pressure, and environmental conditions. Today our Track Washers are certified to the American Railroad Engineering Association (AREA) standards.

Quality is the key. In raw materials, high –grade alloy steel is essential. In production, each stage of the manufacturing process is carefully monitored, controlled, and measured. Final test and inspection are conducted prior to packing. The result is economical spring washers that will prolong life of the rail and joint assemblies while reducing maintenance costs.
