Railway Thread Spike Screw Bolts Track Accessories
1. Brief introduction:
Railway Threaded Spike is a core fastener for railway systems, connecting rails, base plates and sleepers. It bears train loads, ensures track stability and adapts to high-speed, ordinary speed, heavy-haul and turnout scenarios. Our products comply with EN, AREMA, GB/T 3098.1 and TB/T 3395 standards, with customized services available.
2. Core Advantages:
- High Strength: Carbon steel (4.6-4.8 grade) or alloy steel (8.8-10.9 grade), quenched and tempered for excellent tensile and fatigue resistance.
- Corrosion Resistance: Multiple surface treatments for different harsh environments.
- Precise & Firm: Rolled/turned threads for strong anchoring, anti-vibration loosening.
- Wide Adaptability: Suitable for wooden/concrete sleepers, with adjustable track gauge and height.
3. Production & Quality Control
Strict process: Raw Material Inspection → Cutting & Forming → Thread Processing → Heat Treatment → Surface Treatment → Comprehensive Quality Inspection.
All products are qualified before delivery.
