Screw spikes form a secure threaded connection with wooden or concrete sleepers to ensure rail stability under heavy load and high-speed operation.
Suitable for high-speed railways, heavy-haul freight lines, urban metro systems, and industrial railways. Can be used with spring washers, rail clip systems, or plastic dowels to secure and position rails on sleepers, enhancing durability and operational safety.
Standards and specifications
The design and manufacturing of railway standard railroad screw spikes must comply with corresponding national and international standards. These standards have clear requirements for the material, mechanical properties, dimensional tolerances, anti-corrosion treatment, etc. of railway screw spikes.
- Chinese standards: TB/T 1495 (railway standards and specifications), GB/T 1346, etc.
- American standards: ASTM A66, AREMA (American Railroad Engineering and Maintenance Association standards).
- European standards: EN 13481, UIC 864-2, etc.
| Type | Ss5, Ss 8, Ss25, Ss36, UIC864-1 Series, etc |
| Raw material | Q235, 35 steel, 45steel, 40Mn2, 20 Mn Si |
| Grade | 4.6, 4.8, 5.6, 8.8 |
| Surface | plain(oiled), black paint, color paint, zinc, HDG, etc |
Produced via hot forging, thread rolling, and mechanical processing with DIN standard testing. Each batch is tested for tensile strength, yield strength, and cold bending performance to meet DIN 5.6 grade requirements.
Surface treatment
To improve the anti-corrosion performance, railway screw spikes are usually surface treated, such as hot-dip galvanizing, electro-galvanizing, Dacromet coating, or other special coating treatments. These treatments can effectively prevent corrosion and aging of railway screw spikes in harsh environments.Commonly used surface treatments: hot-dip galvanizing, electro-galvanizing, Dacromet coating, etc.
