Track bolt is a kind of widely used rail fastener. Track bolt is referred to as rail bolt, used to fasten rail joints to link rails or to fix the sleepers with rails. Track bolts sizes are changing along with the requirements of the rail section. The rail bolts can be classified into several types depending on their fastening ways and applications. Fish bolts, track bolt for rail fastening systems (clip bolt & clamp bolt), track bolts for fastening different running tracks and anchor bolts are four main varieties.
GNEE RAIL can provide track bolts of various specifications. If you have special customization requirements for the products, please contact us.
Fish Bolts
Fish bolts are bolts for fastening fishplates. Railway fishplates are generally used at the joints of two rails on the railway to fix the two sections of steel rails. Fishbolt need to be used in conjunction with nuts. When purchase, please choose the fishbolts that match the aperture size and the thickness of the fishplate.

Rail Bolt for Rail Fastening Systems (clip bolt & clamp bolt)
On the railway line, in order to fix the rail, GNEE RAIL use a unit of rail fasteners (rail fastening system). Such as rail base plate, rail clip, rail clamp, rubber pad, plastic dowel. Clip bolts and clamp bolts are integral to the rail fastening system.
1.Clip bolt
Clip bolt, with the use of rail clip. In the high speed WJ-7 rail fastening system, T-bolt and B1 anchor bolt are required. They need match with elastic rail clips.
2.Clamp bolt
In the KPO clamp rail fastening system, we use HS bolt match with KPO clip.
3.Frog bolt
As an important part of the railway line, railway frog requires the use of special strength of rail bolts, known as frog bolts.
