China Screw Spike Suppliers - Factory Direct Rail Fasteners for EU EN 13481 & US AREMA Compliance
Basic Information
These screw spikes, also called threaded rail spikes, are core anchoring components of EU/US standard compliant rail fastening systems. They are designed to firmly lock base plates, elastic clip assemblies, and other parts to pre-embedded sleeves in concrete sleepers, preventing displacement of the whole fastening system under repeated dynamic train loads.
🌍
EU Standard (EN 13481-2 / EN 14399)
Forged from Grade 4.8/8.8 high-carbon steel. Metric sizes M16 to M27. Compatible with Pandrol Fastclip and Vossloh SKL systems.

US Standard (AREMA Chapter 5)
Standard imperial sizes (5/8’’ to 1’’). Supports up to 40t axle-load heavy-haul freight lines.
🛡️
Anti-Corrosion Coating
Dacromet or hot-dip galvanized finishes. Passed 1200+ hour neutral salt spray tests for extreme environments (-45℃ to 75℃).
⚙️
High Performance
Minimum shear strength of 750MPa. Passes 5 million dynamic load cycle tests. 30+ years service life.
Application & Performance
Our screw spikes are suitable for 350km/h high-speed rails, 25t axle-load heavy-haul lines, and urban transit routes. For electrified lines, insulated coated versions are available, providing ≥12MΩ insulation resistance to avoid railway signal interference. We also offer custom thread specifications, lengths, and surface treatments for special project demands.
