Who We Are?

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

Track Washers
Request a Quote

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.

Track Washer Styles:

  • Improved High Power Spring Washers
  • Pennsylvania Railroad Specifications MW-6 Spring Washers
  • Plain Pattern Square Section Washers
  • Double Coil Improved High Power Spring Washers

Dimensions:

  • Nominal bolt diameters: 15.875 mm (0.625”) thru 76.200 mm (3.0”)
  • Most special dimension washers can be produced to meet customer specifications and tolerances.

Materials

  • High quality, high carbon, boron additive steel

Standards and Specifications

  • AREA 1967, AREA 1933, Pennsylvania Railroad Specification MW-6

Certification

  • Certificate of conformance
  • Chemical and physical certification with complete traceability to melt process
  • Test Certification to specific customer requirements

Quality Control

  • In-Process Controls are employed in all areas of production
  • Other Quality Control Procedures
    • Ductility Test - 90° twist
    • Reactive Pressure Performance Test
    • Permanent Set Test

Packaging

  • All washers packed in 2.5 plastic pails
  • Canisters are palletized and plastic wrapped

Regular SeriesThe tension generated by the deflection of the Regular helical spring lock washer meets the needs of most commercial applications. It is, therefore, the most popular type of helical spring lock washer in terms of usage and production.
