What Is an Oval Neck Track Bolt?
An oval neck track bolt (or oval neck fish bolt) is a high-strength fastening component engineered for railway track connection systems. It features a unique elliptical neck that perfectly matches the elliptical holes in rail fish plates. This anti-rotation design prevents the bolt from spinning during nut tightening and long-term train operation. It provides stable clamping performance, heavy vibration resistance, and overall track structural stability for railway mainlines, sidetracks, and turnout systems.
Signum Rail Fastener China (Kunshan Signum Machinery Technology Co., Ltd.) manufactures these specialized railway fasteners in strict accordance with global standards, including AREMA, UIC, DIN, ASTM, and AS 1085.
