The usage standards for fishtail plugs mainly include the following points:

1. Selection and matching: Select fish tail bolts of appropriate specifications, sizes, and strength levels based on the type of rail and sleeper used, ensuring their compatibility with the track system.

2. Pre installation inspection: Before installation, carefully inspect the appearance of the fish tail bolt to ensure that there are no defects such as cracks, deformation, or thread damage.

3. Cleaning treatment: Clean the installation area to remove debris, rust, and oil stains to ensure good contact and fastening effect.

4. Correct installation: Operate according to the prescribed installation sequence and method, usually requiring the use of specialized tools to accurately insert the fish tail bolt into the installation hole and ensure that it fits tightly with the steel rail and sleeper.

5. Tightening force: Use a torque wrench to tighten according to the specified torque value to ensure even and satisfactory tightening force. Excessive torque may cause bolt damage, while insufficient torque may not achieve the desired tightening effect.

6. Regular inspection: During railway operation, fish tail bolts should be inspected regularly to check for looseness, deformation, rust, and other conditions.

7. Maintenance and replacement: For problematic fish tail plugs, timely maintenance or replacement should be carried out. When replacing, a new fish tail plug that meets the standards should be selected and reinstalled according to the specifications.

8. Storage management: Unused fish tail plugs should be stored properly to avoid moisture, rust, and mechanical damage.

Following these usage guidelines can ensure that fish tail bolts play a good role in railway track connections, ensuring the safety and stability of railway transportation.
