Product Overview: As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Railway Sleeper Spring Clip – a precision-engineered fastening component designed for robust track maintenance. With annual export value exceeding US$5 million and a global footprint spanning North America, Europe, Asia, and beyond, we combine decades of manufacturing expertise with rigorous quality control. This 12mm diameter spring clip delivers a consistent 6kN clamping force, ensuring reliable rail-to-sleeper fixation under heavy loads and dynamic conditions. Our product is fully compliant with international railway standards, backed by a warranty against defects, making it the preferred choice for railway contractors and maintenance teams seeking long-term performance.
Key Features & Technical Specifications
- Diameter: 12mm – optimized for standard rail fastening systems, ensuring compatibility with common sleeper inserts.
- Clamping Force: 6kN – precisely calibrated to maintain proper rail gauge and prevent loosening from vibration and thermal expansion.
- Material: High-quality spring steel (industry standard) – heat-treated for elasticity, fatigue resistance, and long service life.
- Standard Compliance: Meets major railway norms (e.g., TB/T, UIC, AREMA – available upon request) – tested for dimensional accuracy and load performance.
- Surface Finish: Black oxide coating or as specified – corrosion-resistant for outdoor use in various climates.
- Warranty: Defects warranty included – covers manufacturing flaws under normal use for a defined period (details available in contract).
- Customization: Length, surface treatment, and packaging can be customized to meet specific project requirements.

Performance Advantages & Customer Benefits
- Superior Elasticity: The 12mm spring steel design provides optimal flexibility, absorbing dynamic loads and reducing track wear. This translates to longer intervals between maintenance, saving both time and labor costs.
- Consistent 6kN Clamping: Each clip is factory-tested to deliver the exact clamping force, ensuring uniform rail pressure across the entire track. This prevents gauge widenening and reduces the risk of derailments.
- Corrosion Resistance: Standard black oxide finish, with optional zinc plating or Dacromet coating, withstands moisture, salt spray, and chemical exposure – ideal for coastal or tunnel environments.
- Easy Installation: Pre-formed shape allows quick mounting with standard tools, reducing installation time by up to 30% compared to traditional clips. No special equipment required.
- Long Service Life: With a fatigue life of over 3 million cycles, our spring clips typically outlast the rail itself, providing a reliable fastening solution for decades.
- Global Compatibility: Designed to fit common sleeper systems (e.g., concrete, wood, steel) and rail profiles (UIC54, UIC60, etc.). Custom dimensions available to match specific sleeper geometries.
