Track bolts are an essential component of rail infrastructure, responsible for holding the rails and sleepers together to create a stable and safe track system. These bolts are typically used to fasten rails to the sleepers and keep them in place, providing stability and support for the rail line. Without proper installation and maintenance of track bolts, there can be severe consequences for the safety and efficiency of the railway system.
The railway bolts can be classified into several types, such as, Button head oval neck railway bolt, Diamond neck railway bolt, Railway bolt NF F50-008, Fish bolt, Railway bolt of Russian standard, Clip bolt, Clamp bolt and inserted bolt for Russia, anchor bolt, T-bolt clamp and other special Railway bolts, etc.

Material selection is a critical factor in the performance and longevity of track bolts in rail construction. The right material can mean the difference between a safe and reliable rail system and costly maintenance or repairs. When selecting a material for track bolts, it is essential to consider factors such as strength, corrosion resistance, and durability.
According to related rail track standards, each joint needs to be bolted with at least two railway 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 railway bolts.
Railway bolts in use have to be in the proper size and tightly in place.
Railway bolts have to be installed with AREMA spring washers whereas the nuts have to be installed against the spring washer.
Railway bolts have to be installed and the nuts have to installed alternately on the inside and outside of the rail.
When railway 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.
Safety standards require that on operation are permitted over rails where all Railway bolts are missing or ineffective
The Railway bolt consists of a shaft with a wood screw thread on one side and with a metal screw thread on the other, it also features a 7mm hex shape as part of the shaft and using a wrench or ring spanner can be easily wound into the end grain or into the newel post.
