What Is NF F500-15 Double Head Screw Spike?
An NF F500-15 Double Head Screw Spike is a specialized, high-strength threaded fastener for securing railway tracks, featuring threads on both ends for maximum grip, used with systems like the Nabla clip, and conforming to French (NF F500-15) and international standards for railway components, offering superior pull-out resistance compared to traditional spikes.
Key Characteristics of NF F500-15 Screw Spike:
- Standard: Complies with French standard NF F500-15, along with UIC864-1 and ISO898-1, ensuring quality for rail applications.
- Design: Has threads on both ends, allowing it to be driven into sleepers (ties) for excellent holding power in wood or concrete.
- Application: Used in rail fastening systems, often with spring washers and clips, providing strong fixation for rails to sleepers.
- Material & Grades: Made from high-quality steel (like Q235, 35#, 45#) and available in various strength grades (e.g., 4.6, 5.6, 8.8).
- Surface Finishes: Available in plain oiled, zinc-plated, hot-dip galvanized (HDG), or black oxide, among others, for corrosion protection.
- Advantages: Offers significantly higher pull-out resistance (up to double) than dog spikes, reducing maintenance.
