Project Description

Track bolts, also called Rail BoltsFang blots or Rail anchor bolts, is used for fixing rails or chairs to sleepers. The rail bolt is a bolt inserted through a hole in the sleeper with a fanged nut that bites into the lower surface of the sleeper. 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 the rail. They are thought more effective than rail spikes and screw spikes and so are used in positions such as switch (point) tie plate and on sharp curves.
