Railway Track Bolt
Rail track bolts are high-strength fasteners securing rails to sleepers (ties) and joining rail sections via fish plates. Made of 10.9/12.9 grade alloy steel (with phosphated or galvanized coatings for corrosion resistance), they withstand extreme dynamic loads, vibration, and temperature fluctuations. Standards like ISO 898-1 dictate tensile strength (≥1000MPa) and thread precision for secure clamping.
