About Fish Bolts Nuts

Square head bolts and nuts used for rails are commonly referred to as railway track bolts or fish bolts. These fasteners are specifically designed for high-strength, heavy-duty applications in rail track systems to connect steel rails together and prevent movement caused by the vibration and load from passing trains.

Key Details and Applications

Function: The primary purpose is to create secure and durable connections within railway infrastructure, such as fastening the rail to the sleeper (cross tie) or joining two sections of rail using a fish plate (joint bar).
Design: The square head design provides several advantages, including:
- Secure Grip: The square shape offers four distinct contact points for a wrench, providing a firm grip that is ideal for manual installation and minimizes slippage.
- Anti-Rotation: When installed in a corresponding square hole or slot, the square section under the head grips the material, preventing the bolt from turning when the nut is tightened.
- High Strength: These bolts are typically made from high-strength steel (e.g., Grade 8.8, 10.9) to withstand significant tension and pressure in demanding environments.
