Hot Dip Galvanized Grade 4.6,4.8,5.6,5.8,8.8 Double Head Screw Spike
Oct 23, 2025
A railway screw spike is a type of fastener used in railway construction to fix steel rails to railway sleepers (also known as ties). Unlike traditional spikes, railroad screw spikes have a threaded design, which provides a more secure and durable fastening by embedding into the sleeper material (typically wood or concrete). They are designed to withstand the dynamic loads and vibrations caused by passing trains.
The hot dip galvanized multi-grade double head screw spike is an essential fastener in railway track fastening systems, used to securely attach rails to sleepers, ensuring stability and safety during train operations. The double-head design provides bi-directional clamping force, tightly connecting the rail, sleeper, and tie plate, enhancing pull-out resistance and overall track stability. The multiple grades (4.6, 4.8, 5.6, 5.8, 8.8) cater to different track load requirements, suitable for conventional, high-speed, and heavy freight railway construction.

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.
Choosing railway screw spikes that meet the standards can not only ensure the safety and stability of the track but also extend the service life of the track system and reduce overall maintenance costs. GNEE RAIL provides a variety of railroad screw spike products that comply with international standards to meet the needs of different railway projects.
