    Fish tail bolt, also known as fish tail bolt or fish tail screw, is a commonly used fastener for railway track connections.

     

    Its shape resembles a fish tail, hence its name. Fish tail plugs are usually made of high-strength steel, which has good tensile strength and fatigue resistance.

     

    Its main function is to tightly connect the steel rails and sleepers together, ensuring the stability and safety of the railway track. The specifications and dimensions of fish tail bolts may vary depending on the type of steel rail and sleeper.

     

    When installing and using fishtail bolts, it is necessary to strictly follow relevant standards and specifications to ensure their fastening effect and the safety and reliability of railway operation.
