Application Criteria of Track Bolts


According to related rail standards, each joint needs to be bolted with at least two bolts in each rail tightened to approximately 400 foot-pounds of torque which develops between 25,000, and 30, 000 pounds of tension in the bolts.

  1. Bolts in use have to be in the proper size and tightly in place.
  2. Bolts have to be installed with AREMA spring washers whereas the nuts have to be installed against the spring washer.
  3. Bolts have to be installed and the nuts have to installed alternately on the inside and outside of the rail.
