Rail bolts also called track bolts, are used to fasten steel rail ends together at a joint. The sizes of track bolts are varying with the requirements of the section of rail. The proper diameter and length of the track bolt can be determined by checking the applicable railway standard.
According to related rail standards, each joint needs to be bolted with at least two track 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.
