As a leading manufacturer of railway fastening components since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Spring Steel W-Type Elastic Rail Clip designed to meet the strict UIC 864 standard. With a precise 12 mm diameter and controlled hardness of HRC 44-48, this rail clip delivers consistent elastic clamping force, ensuring long-term track stability and reduced maintenance costs. Our products are exported to over 15 countries across North America, Europe, Southeast Asia, and Africa, with annual export value exceeding US$5 million. We combine decades of manufacturing experience with advanced heat treatment processes to produce rail clips that withstand heavy loads, temperature variations, and dynamic stresses.
Product Features & Technical Specifications
- Material Excellence: Manufactured from premium spring steel (60Si2Mn or 55Si2Mn), offering high fatigue strength and resilience.
- UIC 864 Compliance: Fully conforms to UIC 864 dimensional and mechanical requirements, ensuring interchangeability with existing systems.
- Optimized Hardness: HRC 44-48 hardness range provides the ideal balance between elasticity and wear resistance, preventing premature failure.
- Precision 12 mm Diameter: The wire diameter is strictly controlled to ±0.2 mm, guaranteeing consistent clamping force across all clips.
- Elastic W-Type Design: The W-shape geometry allows for easy installation and removal while maintaining firm rail retention.
- Corrosion Protection: Standard surface treatment is black oxide or phosphating; additional options like Dacromet or hot-dip galvanizing are available upon request.
- Compatibility: Suitable for UIC 60, UIC 54, and other standard rail profiles when used with appropriate base plates and insulators.
- Quality Assurance: 100% dimensional inspection and hardness testing before shipment, with traceable batch numbers.

Frequently Asked Questions (FAQ)
Q1: Is this rail clip compatible with UIC 60 rail?
A: Yes, the W-type elastic clip is designed for use with UIC 60 and UIC 54 rail profiles, provided the correct base plate and insulator system is used. Our technical team can confirm compatibility for your specific rail type.
Q2: What is the lead time for an order of 10,000 pieces?
A: Typically 20–30 days after deposit confirmation, depending on production load. For urgent orders, we can expedite to 15 days with a small surcharge.
Q3: Do you provide a certificate of material and hardness test report?
A: Yes, we can provide a mill test certificate for each batch, including chemical composition, mechanical properties, and hardness test results. This is included at no extra cost.
Q4: Can the surface treatment be customized to meet specific corrosion resistance requirements?
A: Absolutely. Standard finishes are black oxide and phosphating. We also offer Dacromet, zinc-nickel plating, or hot-dip galvanizing on request. Lead time and pricing may vary.
Q5: How do you ensure the hardness is consistently within HRC 44-48?
A: We use a controlled quenching and tempering process with continuous monitoring. Each batch is sampled and tested using a Rockwell hardness tester. We maintain a 95% confidence level within the specified range.
Q6: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 2,000 pieces for stock sizes. For trial orders, we can accept 500 pieces at a slightly higher unit price. Contact our sales team for details.
Q7: Can you provide samples for testing before mass production?
A: Yes, we offer free samples (up to 5 pieces) for qualified customers. You only need to pay the shipping cost. Please send your inquiry with your company details and intended application.
Q8: How do you pack the rail clips for export?
A: Standard packing is in woven bags or bulk on pallets, with steel strapping. For moisture-sensitive areas, we can use VCI paper or sealed plastic bags. Custom marking and labeling are available.
