As a leading manufacturer with over 25 years of expertise in railway fastening components, Anping County Boli Hardware Wiremesh Products Factory proudly presents the M24 Spring Steel Elastic Rail Fastening Assembly designed specifically for UIC60 rails. This assembly delivers a precise 60kN clamp force, ensuring reliable track stability and safety for heavy-duty railway operations. Our product is engineered to meet the demanding requirements of modern rail systems, offering exceptional durability and ease of installation.
Manufactured in our ISO 9001-certified facility in Hengshui, Hebei, China, each component undergoes rigorous quality control to guarantee consistent performance. With an annual export value exceeding US$5 million and shipping to over 15 global markets, our fastening assemblies have been trusted by railway operators worldwide. The M24 assembly combines robust spring steel construction with advanced elastic design to maintain optimal clamping force under dynamic loads.
Key features of the M24 Elastic Rail Fastening Assembly include:
- Material: High-quality spring steel (60Si2MnA or equivalent) for excellent fatigue resistance and elasticity.
- Clamp Force: Exactly 60kN per assembly, ensuring secure rail fixation while allowing necessary vertical and lateral adjustments.
- Rail Profile Compatibility: UIC60 (60 kg/m) rail standard, widely used in mainline and high-speed railways.
- Corrosion Protection: Standard black oxide finish with optional hot-dip galvanizing or Dacromet coating for harsh environments.
- Easy Installation: Pre-assembled components (clip, shoulder, insulator, and bolt) reduce on-site labor and installation time.
- Low Maintenance: Elastic design minimizes loosening and reduces the need for periodic retightening.
The technical specifications of the M24 Assembly are as follows:
| Parameter | Value |
| Rail Profile | UIC60 |
| Clamp Force (kN) | 60 |
| Bolt Size | M24 |
| Spring Steel Grade | 60Si2MnA (or equivalent) |
| Tensile Strength (MPa) | ≥ 1570 |
| Surface Treatment | Black oxide (standard), hot-dip galvanized (optional) |
| Weight per Set (approx.) | 2.5 kg |
| Packaging | Wooden pallets (500 sets/pallet) or as per customer request |
The M24 assembly is designed to deliver long-term benefits for railway operators:
- Enhanced Safety: Consistent 60kN clamping force prevents rail creep and gauge widening, reducing derailment risk.
- Cost-Efficiency: Durable spring steel extends service life up to 15-20 years, minimizing replacement costs.
- Compatibility: Works seamlessly with standard UIC60 rail and concrete sleepers, with optional insulators for electrified tracks.
- Global Compliance: Meets AREMA, UIC, and GB/T standards (available upon request).

Frequently Asked Questions (FAQ)
Q1: What is the exact clamp force of the M24 assembly?
The M24 assembly provides a nominal clamp force of 60 kN when properly installed as per our torque specifications. The actual force may vary within ±5% due to manufacturing tolerances.
Q2: Is this product compatible with other rail profiles besides UIC60?
This assembly is specifically designed for UIC60 rails. For other rail profiles (e.g., UIC54, 115RE), we can customize the components upon request.
Q3: What surface treatments are available?
Standard treatment is black oxide. Optional treatments include hot-dip galvanizing, Dacromet, or zinc-nickel plating for enhanced corrosion resistance. Please specify your requirements.
Q4: How do you ensure consistent quality?
We have a comprehensive quality management system. Each batch is tested for hardness, tensile strength, and clamp force. We also provide material certificates and test reports upon request.
Q5: What is the typical lead time for bulk orders?
For standard orders (10,000-50,000 sets), lead time is 20-30 days. For larger quantities, it may extend to 45 days. We can arrange partial shipments for urgent needs.
Q6: Do you provide samples for testing?
Yes, we offer free samples (shipping charges apply) for evaluation. The sample lead time is 7-10 days.
Q7: Can the assembly be used in electrified railway lines?
Yes, with optional insulating components (rail pads and insulator clips) that are available upon request. These ensure electrical insulation between rail and sleeper.
Q8: What packaging options do you offer for export?
We pack in wooden pallets wrapped with stretch film, with each pallet containing 500 sets. Corrugated cartons or steel crates are also available for special requirements.
