Rail Bolt for Rail Fastening Systems (clip bolt & clamp bolt)
On the railway line, in order to fix the rail, we 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.
