Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a trusted manufacturer of railway fastening components. We proudly present our Boltless Rail-to-Sleeper Fastening System—a revolutionary solution designed for rapid installation and superior track stability. Engineered with premium spring steel clips and 8.8 grade bolts, this system offers a perfect balance of strength, durability, and ease of use. Ideal for 60E1 rail profiles, it significantly reduces labor time and maintenance costs, making it an excellent choice for modern railway projects worldwide.
Our boltless design eliminates the need for traditional threaded fasteners, allowing for faster assembly and disassembly without compromising clamping force. The spring steel clips provide consistent elastic pressure, ensuring secure rail fixation while absorbing vibrations and thermal expansion. Combined with high-strength 8.8 grade bolts, this system delivers reliable performance under heavy loads and harsh environmental conditions. Whether you're building new lines or upgrading existing tracks, our fastening system enhances operational efficiency and safety.
Key Features & Technical Specifications
- Boltless Installation: No tools required for rail-to-sleeper fixation—simply clip and lock, reducing installation time by up to 50%.
- Spring Steel Clips: Made from high-quality spring steel (60Si2Mn or equivalent), offering excellent fatigue resistance and long service life.
- 8.8 Grade Bolts: High tensile strength bolts used for accessory connections, ensuring robust fastening under dynamic loads.
- Compatible with 60E1 Rail: Designed specifically for 60E1 (UIC60) rail profile, but customizable for other rail types upon request.
- Quick Maintenance: Simple clip replacement without disturbing sleepers, reducing track downtime.
- Corrosion Protection: Clips and bolts are treated with anti-rust coating (e.g., black oxide, galvanized) for extended durability in outdoor environments.

The boltless design significantly reduces the complexity of track laying. Traditional fastening systems require multiple bolts, nuts, and washers, leading to longer installation times and higher labor costs. Our system uses a unique clip mechanism that locks into the sleeper insert, providing a secure hold without any additional fasteners. The spring steel clip maintains constant pressure, preventing rail creep and reducing the need for periodic retightening. 8.8 grade bolts are used only for the clip-to-sleeper attachment (if required) or for accessory components, ensuring high reliability in critical connections.
Additionally, this system is designed for easy maintenance. In case of clip wear or damage, the clip can be replaced in seconds using a simple tool, without needing to remove the rail or disturb adjacent sleepers. This minimizes track downtime—a key advantage for busy railway lines. The corrosion-resistant coating ensures long-term performance even in coastal or humid environments.
Why Choose Our Boltless Fastening System?
- Time Savings: Installation is 2–3 times faster than conventional bolt systems, reducing project costs.
- Lower Maintenance: The self-locking clip design eliminates bolt loosening, reducing inspection frequency.
- Enhanced Safety: Consistent clamping force prevents rail buckling and gauge widening.
- Versatility: Can be used with concrete, steel, or wooden sleepers (with appropriate inserts).
- Eco-friendly: No need for lubricants or anti-seize compounds, reducing environmental impact.

Frequently Asked Questions
-
Q: Is this system truly boltless? Why does it include 8.8 grade bolts?
A: The rail-to-sleeper fixation is boltless—the clips snap directly into the sleeper insert. The 8.8 grade bolts are used for optional accessory components (e.g., tie plates or gauge rods) or for custom configurations where additional clamping is required. The core fastening mechanism does not require bolts. -
Q: What rail profiles are compatible?
A: It is specifically designed for 60E1 (UIC60) rail. However, we can customize clips for other profiles like 54E1, 50E1, or ASCE 60 upon request. -
Q: How long does installation take for a standard track section?
A: With two workers, a 100-meter track section can be installed in approximately 1–2 hours, depending on sleeper spacing. This is 50% faster than traditional bolt systems. -
Q: What is the expected service life of the spring steel clips?
A: Under normal operating conditions, the clips can last 10–15 years before requiring replacement. The fatigue life exceeds 1 million cycles in testing. -
Q: Can this system be used on curved tracks?
A: Yes, it is suitable for curves with a radius of 300 meters or more. For tighter curves, we recommend additional gauge ties or custom clip placement. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples for qualified buyers. Please contact us with your shipping details and application requirements. -
Q: What is the minimum order quantity?
A: For standard sizes, MOQ is 500 sets. Custom orders may have different MOQs—please inquire. -
Q: How do I maintain the system?
A: Regular visual inspection of clips and bolts is recommended every 6 months. Replace any worn or damaged clips immediately. The system requires no lubrication.
