Railway Track bolts are used to fasten 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.

The track bolts can be classified into several types, such as, Button head oval neck track bolt, Diamond neck track bolt, Rail bolt NF F50-008, Fish bolt, Track bolt of Russian standard, Clip bolt, Clamp bolt and inserted bolt for Russia, , anchor bolt, T-bolt clamp and other special bolts, etc.

Application 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.
4. When bolts and joint bars are moved away, the joint area of the rail and the contact surface of the joint bar have to be cleaned and the joint bar and the bolt threads have to be lubricated.
