Track Bolts & Rail Bolts

Otherwise known as Crawler Track Bolts,  fang bolts, or rail anchor bolts, Track Bolts often secure together treads on crawler tractors and off-road machinery. Which are used to fasten rail ends together at a joint. or fix steel rails and rail chairs to rail ties. The track bolt is a bolt inserted through a hole in the rail tie with a fanged nut that embeds into the lower surface of the tie, With their specifically designed domed hex head cap screws, the bolts are more wear and impact resistant, allowing them to survive extreme circumstances
