Product Overview
Rail fish plate bolts (also called joint bolts) are high-strength fasteners used to secure fishplates (joint bars) at rail joints, ensuring track alignment, structural integrity, and electrical continuity in railway systems. These bolts are designed to withstand dynamic loads, vibrations, and environmental stress.
High Tensile Strength
Grade 8.8, 10.9, or 12.9 steel
Corrosion Resistance
Hot-dip galvanized (HDG), Dacromet, or stainless steel
Vibration Resistance
Double nuts, spring washers, or thread-locking adhesive
