Fishbolt (also known as fish tail bolt, rail joint bolt) is a critical fastener designed exclusively for railway track systems. It secures fishplates (joint bars) to connect two rail sections, ensuring stable, safe, and durable rail joints under heavy train loads and vibrations.
Manufactured via hot forging + heat treatment, our fishbolts deliver exceptional tensile strength, vibration resistance, and corrosion protection. Ideal for mainline railways, industrial tracks, mining rails, and metro systems.
