China Rail Bolt Suppliers - High Strength Fasteners for Compliance with EU EN 13481 & US AREMA Standards from Factory
Basic Information
These bolts are core load-bearing fastening parts of EU/US standard compliant rail fastening systems, tasked with securing elastic clips, base plates and other components firmly to concrete or wooden sleepers, maintaining stable clamping force of the whole fastening system under long-term dynamic train loads.
Global Standards
Fully compliant with EN 13481, EN 14399 (EU) and AREMA Chapter 5 (US) specifications.
High Strength
Available in Grade 8.8/10.9 alloy steel and Grade 5/8 carbon steel for heavy-haul lines.
Anti-Corrosion
Dacromet or hot-dip galvanized coating, passing 1200+ hour neutral salt spray tests.
Extreme Durability
Operates from -40℃ to 80℃ and survives 3 million vibration cycles without loosening.
Suitable for 350km/h high-speed rails and up to 40t axle-load heavy-haul freight lines, these bolts are fully compatible with mainstream Pandrol Fastclip and Vossloh SKL fastening systems. Anti-loosening designs including nylon insert and crimped point are applied to guarantee operation safety. Insulated coating versions (≥10MΩ) are also available to avoid railway signal interference.
