China Factory Screw Spike Suppliers for EU EN 13481 & US AREMA Rail Fasteners - High Shear Strength & Anti-Corrosion Performance
These screw spikes, also called threaded rail spikes, are core anchoring components of EU/US standard compliant rail fastening systems, 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 Standards
Conforming to EN 13481-2 and EN 14399. Forged from Grade 4.8/8.8 steel, sizes M16 to M27.
US Standards
Following AREMA Chapter 5. Imperial sizes 5/8’’ to 1’’ for up to 40t axle-load.
Durability
750MPa shear strength. 5 million dynamic load cycles without fracture.
Adaptability
Operating range -45℃ to 75℃. Dacromet or HDG anti-corrosion coating.
Qualified products guarantee over 30 years of service life and are fully compatible with mainstream Pandrol Fastclip and Vossloh SKL fastening systems.
All products pass 1200+ hour neutral salt spray tests to adapt to extreme working environments. Insulated coated versions are also available for electrified lines, providing ≥12MΩ insulation resistance to avoid railway signal interference. Custom thread specifications, lengths, and surface treatments are available for special project demands.
