Square Head Fish Bolt technical parameter
Square head fish bolts are a type of fastener used in railway track construction to connect rail sections through joint bars or fishplates. Square head fish bolts feature a square-shaped head, which provides a surface for tightening the bolt using tools such as wrenches or spanners. The square head design allows for greater torque application during installation and removal compared to other bolt head shapes.
Square head fish bolts are commonly used in railway tracks where joint bars or fishplates are employed to connect rail sections. They provide a reliable means of joining rails, contributing to the stability and safety of the railway track.
The dimensions of square head fish bolts can vary depending on factors such as rail type, track design, and specific application requirements.
