Track bolts (also called fishplates bolts or railway anchor bolts) are used to fix steel rails or rail tie plates to cement or wooden sleepers, or to fix the connection between rail fishplates and steel rails.
The size of the track bolts varies with the requirements of the rail section. The proper track bolt diameter and length can be determined by checking the applicable railway standards.
Track bolts can be divided into several types, for example, 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. To fix a flat-bottomed rails, an upper-lipped washer can be used to grip the edge of the rail. They are more resistant to rail loosening due to vibration or movement. In actual use, they are more effective than crawler spikes and screw spikes, so they can be used in places such as turnouts (points) tie plates and turns.
