Overview of fishtail bolts
Fishtail bolts (fishtail wires) are mostly used in the connection of track joint splints (fishtail plates) for fixing, and sometimes hexagonal bolts can be used instead.
Usage of fishtail bolts
Fishtail bolts are mainly used in track laying in the metallurgical industry, coking industry, and iron and steel industry, and the rail and rail joints are connected and fastened.
Type and material of fishtail bolts
Models are Φ14×70, Φ16×75, Φ18×90, Φ20×90, Φ22×135, Φ24×135, Φ24×145, Φ24×170, etc. Generally, it is hot-pressed by friction press, the buckle length is 50mm, and there are also cold Upsetting is mostly used in the connection of rail joints.
Materials are: Q235 and 45# steel and insulated fishtail bolts, etc.
Bolts, mechanical parts, cylindrical threaded fasteners with nuts. Bolt: A type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Fishtail bolt grades:
According to relevant standards, the bolt performance grades are divided into more than 10 grades such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Among them, the bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel and are heat-treated. (quenching, tempering), commonly known as high-strength bolts, the rest are commonly known as ordinary bolts. The bolt performance grade label consists of two parts of numbers, which represent the nominal tensile strength value and yield ratio of the bolt material respectively.
For example:
Bolts of property class 4.6 mean:
1. The nominal tensile strength of the bolt material reaches 400MPa;
2. The yield-strength ratio of the bolt material is 0.6
3. The nominal yield strength of the bolt material reaches 400×0.6=240MPa
Performance level 10.9 high-strength bolts, after heat treatment :
1. The nominal tensile strength of the bolt material reaches 1000MPa;
2. The yield-strength ratio of the bolt material is 0.9;
3. The nominal yield strength of the bolt material is 1000×0.9=900MPa
Bolt performance grade is an international standard. Bolts of the same performance grade, regardless of the difference in material and origin, have the same performance, and only the performance grade can be selected in the design.
The 8.8 and 10.9 strength grades mean the shear stress resistance of the bolt is 8.8GPa and 10.9GPa
8.8 Nominal tensile strength 800N/MM2 Nominal yield strength 640N/MM2
