Fish bolt (also known as a rail joint bolt) is a specialized fastener used to secure fishplates (joint bars) to the ends of rails in railway tracks. Fish bolts play a critical role in maintaining the alignment and integrity of rail joints, ensuring smooth and safe train operations. They are designed to withstand high tensile and shear forces, making them essential components in railway infrastructure.
Key Features
Material
Made from high-strength steel or alloy steel to handle heavy loads and dynamic forces.
Often heat-treated to enhance strength and durability.
May be coated with anti-corrosion treatments, such as galvanizing, to improve longevity.
Design
Hexagonal or square head for easy installation using a wrench or specialized tools.
Threaded shank to securely fasten fishplates to the rails.
May include a nut and spring washer to prevent loosening due to vibrations.
competitive advantage
High Tensile Strength
Capable of withstanding the dynamic forces exerted by passing trains.
Secure Connection
Ensures that fishplates remain tightly fastened to the rails, maintaining alignment and track integrity.
Durability
Resists wear, corrosion, and environmental degradation, ensuring a long service life.
Resistance to Vibration
Less likely to loosen due to train vibrations, reducing maintenance needs.
