About Our Product
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of precision rail fastening components. Our 12.9 Grade Alloy Steel Rail-to-Sleeper Elastic Clip with Black Oxide Finish is designed to deliver reliable performance in demanding railway environments. With an annual export value of US$5 million to US$10 million and shipments to over 20 countries including North America, Europe, Southeast Asia, and Africa, we understand the importance of quality and consistency. This elastic clip combines high-strength alloy steel with a durable black oxide coating, ensuring long service life and secure rail fixation. Whether you are maintaining existing tracks or building new lines, our product meets the rigorous standards of modern rail infrastructure.
Key Features & Technical Specifications
Our elastic clip is manufactured from premium alloy steel (commonly 40Cr or 35CrMo) and heat-treated to achieve the 12.9 grade strength level. The black oxide finish provides excellent corrosion resistance and reduces friction during installation. Below are the core technical parameters:
| Parameter | Value |
|---|---|
| Material | Alloy Steel (40Cr, 35CrMo or equivalent) |
| Grade | 12.9 (tensile strength ≥1200 MPa, yield strength ≥1080 MPa) |
| Surface Treatment | Black Oxide (thickness 2-5 μm, meets corrosion resistance test) |
| Hardness | HRC 38-44 (after heat treatment) |
| Elastic Deflection | ≥5mm (under specified load, depending on design) |
| Fatigue Life | ≥3 million cycles (tested per EN 13146-5) |
| Operating Temperature | -40°C to +80°C |
| Applicable Rail Types | UIC 60, UIC 54, 50 kg/m, 60 kg/m, and other standard profiles |
Product Advantages & Customer Benefits
- High Strength & Durability: The 12.9 grade alloy steel ensures the clip can withstand heavy loads and repeated stress without permanent deformation. This reduces maintenance frequency and extends track life.
- Excellent Corrosion Resistance: The black oxide finish forms a protective layer that resists rust and environmental degradation, even in humid or coastal areas. This is critical for long-term outdoor use.
- Consistent Elasticity: Each clip is heat-treated and tested to provide uniform clamping force, ensuring secure rail-to-sleeper connection while allowing for thermal expansion and vibration absorption.
- Easy Installation: The clip design allows for simple manual or mechanical installation, reducing labor time and cost. No special tools required for standard applications.
- Customizable Dimensions: We offer flexible sizing options to match different sleeper types (wood, concrete, steel) and rail profiles. Contact us for tailored solutions.
- Quality Assurance: Our factory operates under strict quality control procedures, including material inspection, dimensional checks, and fatigue testing. Every batch is traceable.

Frequently Asked Questions (FAQ)
- What is the difference between 12.9 grade and lower grades? 12.9 grade has a minimum tensile strength of 1200 MPa, making it suitable for high-stress railway applications. Lower grades (e.g., 8.8 or 10.9) may not provide sufficient clamping force for heavy rail systems.
- Is the black oxide finish environmentally friendly? Yes, the black oxide process uses no harmful heavy metals and produces a non-toxic coating. It is compliant with RoHS and REACH regulations (available upon request).
- Can this clip be used with concrete sleepers? Absolutely. The clip is designed to fit standard concrete sleeper shoulders and is compatible with most rail fastening systems (e.g., Vossloh, Pandrol, Nabla).
- Do you offer samples for testing? Yes, we provide free samples for qualified customers. Please contact our sales team with your specific requirements and shipping details.
- What is the typical lead time for bulk orders? For standard sizes, lead time is 15-25 working days after order confirmation. Customized products may require 30-45 days depending on complexity.
- How are the clips packaged for export? They are packed in reinforced cartons or wooden pallets, with rust-proof paper and plastic wrapping. Each package is labeled with product specification and batch number.
- Do you have any quality certificates? Our factory follows ISO 9001 quality management system standards. Specific product tests (e.g., fatigue, corrosion) can be provided upon request.
- Can I get a custom design for a non-standard rail profile? Yes, we can customize the clip dimensions and material composition to meet your requirements. Please provide drawings or samples for evaluation.
