Rail Bolt

Track bolts are used to fasten rail ends together at a joint. The track bolt is a bolt inserted through a hole in rail tie with a fanged nut that embeds into the lower surface of the tie. 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.

Track bolts can be divided into several types, we have different types of track bolts,such as, button head oval neck track bolt, diamond neck track bolt, rail bolt NF F50-008, fish bolt, Russian standard track bolts, clip bolt, clamp bolt and inserted bolt for Russia, , anchor bolt, T-bolt clamp and other special bolts, etc. For fastening flat-bottomed rails, an upper-lipped washer can be used to grip the edge of the rail. They are more resistant to loosening by vibrations and movement of steel rails. In actual use, they are more effective than track spikes and screws and so are used in positions such as switch (point) tie plates and on sharp curves.
