Rail Bolt Suppliers from China - High Strength Fasteners Meeting EU EN 13481 & US AREMA Standards
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 EU EN 13481/EN 14399 and North American AREMA Chapter 5 specifications.
💪
High Strength
Available in Grade 8.8/10.9 alloy steel (EU) and Grade 5/8 carbon steel (US) for heavy-haul lines.
🛡️
Extreme Durability
Dacromet or hot-dip galvanized coatings passing 1200+ hour salt spray tests for -40℃ to 80℃ environments.
⚡
Signal Safety
Insulated coating versions with ≥10MΩ resistance to prevent railway signal interference.
For EU markets, standard thread sizes range from M16 to M24, suitable for 350km/h high-speed rails and 25t axle-load heavy-haul lines, fully compatible with mainstream Pandrol Fastclip and Vossloh SKL fastening systems. For North American markets, unified thread specifications match AREMA standard tie plate and pre-embedded sleeve dimensions for 40t axle-load heavy-haul freight lines. Anti-loosening designs including nylon insert and crimped point are applied, passing 3 million vibration cycle tests without loosening to guarantee operation safety.
