Product Description

 

 

Rail bolt,also called track bolt, it is a kind of fasteners to fix the steel rails to the sleepers. In general, the rail bolt has two parts, the head and screws. Track bolt and nuts are two closed parts. Together with the nuts, the rail bolt can fasten the rails at a joint. The rail bolt and some others fasteners like rail clamp, rail spike, rail clips and the like constitute the rail fastening system. As a rail fastener, it plays a big role in guiding the train. Besides, all the fastening system bears the enormous pressure of trains and their loads. So the each fastener should have enough high strength and stability to ensure the train runs safely and steady even if the train at the highest speeds.
Rail bolt is one of the most important railway fasteners in railway system. In general, railway bolts are used to fasten rail track ends together at a joint. The sizes of railway bolts are varying with the requirements of the section of steel rail. The proper diameter and length of the railway bolt can be determined by checking the applicable railway standard.
In traditional railway bolts once the shaft is wound into the end grain and joined to the second member is necessary to place a washer and a nut on to the end of the bolt shaft and tighten, here lies the difficulty and frustration but not with the Railway bolt. The Railway bolt housing has a special open channel feature in the housing which allows the housing to simply drop of the bolt shaft and commence tightening using a hex bit or Allen key without fiddling and trying to start a nut in a restrictive small hole with the further difficulty in trying to tighten the nut.
