What are Bolts in Railway Tracks?
Bolts in railway tracks, also called track bolts, are used to fasten the ends of the rails together at the rail joints.
Size of Bolts in Railway Tracks
The size of the rail bolt varies with the requirements of the rail section. The proper track bolt diameter and length can be determined by checking the applicable railway standards.
Advantages of Railway Track Bolts:
1. The hole preparation is the same as traditional/old rail bolts
2. Convenient and quick to use.
3. Save time and money
Types of Railway Track Bolts
Track bolts can be divided into round head oval neck track bolts, diamond neck track bolts, track bolts NF F50-008, fishtail bolts, Russian standard track bolts, clamp bolts, clip bolts and insert bolts. Russia, special bolts such as anchor bolts, T-clamp bolts, etc.
1.Fish bolt
Fishtail bolts are bolts used to fasten fishplates. Railway fishplates are generally used at the junction of two rails on the railway to fix two sections of rails. Fishbolt needs to be used in conjunction with the nut. When purchasing, please choose fishtail bolts that match the hole size and thickness of the fishplate.

2. Rail bolts (chuck bolts and chuck bolts) for rail fastening systems
On railway lines, in order to fix the rails, we use a single unit rail fastener (rail fastening system). Such as rail tie plates, rail clips, rail clips, rubber pads, plastic dowels. Clip bolts and clamping bolts are part of the rail fastening system.
1) Clip bolt
Clip bolts, used with rail clamps. In the high-speed WJ-7 rail fastening system, T-bolts and B1 anchor bolts are required. They need to match the elastic rail clip.
2) Clamping bolt
In the KPO clamp rail fastening system, we use HS bolts to mate with KPO clamps.
3) Frog bolt
As an important part of railway lines, railway frog needs to use rail bolts with special strength, called frog bolts.
1) BHON track bolt& Square head frog bolt
Size: Dia.3/4"-1-1/8", Length1-1/2"-6-1/2"
