As a leading manufacturer with over 20 years of experience in metal fastening solutions, Anping County Boli Hardware Wiremesh Products Factory proudly introduces our Spring Rail Clip with Adjustable Clamping Range. Crafted from premium Spring Steel and hardened to 10.9 grade, this rail clip is engineered to deliver consistent clamping force across various rail profiles, ensuring reliable track stability and extended service life. Our factory, established in 1998, combines advanced production techniques with rigorous quality control to provide a product that meets the demanding needs of global railway projects.
The adjustable clamping range sets this clip apart from conventional fixed‑type fasteners. It allows installers to fine‑tune the clamping pressure according to the specific rail type and environmental conditions, reducing the risk of rail creep and minimizing maintenance frequency. Whether you are laying new tracks or upgrading existing infrastructure, this spring rail clip offers a versatile and cost‑effective solution.
Key Features & Technical Specifications
- Material: High‑quality spring steel (60Si2Mn or 55Si2Mn) – excellent fatigue resistance and elasticity.
- Hardness: 10.9 (Rockwell C 38–42) – ensures long‑term durability under heavy loads.
- Adjustable Clamping Range: Designed to fit rail heads from 60mm to 75mm width (customizable upon request).
- Surface Treatment: Available in black oxide, phosphating, or Dacromet coating for corrosion resistance.
- Compatibility: Works with UIC54, UIC60, P50, P65, and other standard rail profiles.
- Installation: Simple snap‑on design – no special tools required.
- Packaging: Securely packed in pallets, cartons, or steel drums to prevent deformation during transit.
Performance Parameters (Typical Values)
| Parameter | Value |
| Clamping Force (kN) | 12 – 18 (adjustable) |
| Fatigue Life (cycles) | ≥ 3 × 10⁶ |
| Elastic Deflection (mm) | 5 – 8 |
| Weight per piece (kg) | 0.35 – 0.55 |
| Operating Temperature (°C) | -40 to +80 |
Advantages for Your Railway Project
- Enhanced Safety: The adjustable clamping range ensures optimal rail‑to‑tie force, reducing the risk of derailment.
- Reduced Maintenance: High fatigue life and corrosion resistance mean fewer replacements over the track’s lifespan.

Frequently Asked Questions
-
Q: What is the exact material of your spring rail clip?
A: The clip is manufactured from high‑grade spring steel, typically 60Si2Mn or 55Si2Mn, which offers excellent elasticity and fatigue resistance. The exact composition can be adjusted per customer request. -
Q: How does the adjustable clamping range work?
A: The clip design incorporates a contoured shape that allows the clamping force to be varied by changing the position of the clip relative to the rail foot. Our technical datasheet provides the recommended settings for different rail profiles. -
Q: Is the hardness 10.9 equivalent to Rockwell hardness?
A: Yes, the 10.9 hardness grade corresponds to a Rockwell C hardness of approximately 38–42 HRC, providing a balance of strength and ductility. -
Q: Can I get samples before placing a bulk order?
A: Absolutely. We offer free samples (shipping charges apply) for quality evaluation. Lead time for samples is typically 5–7 working days. -
Q: What surface treatments are available?
A: Standard treatments include black oxide and phosphating. For higher corrosion protection, Dacromet coating is available upon request. -
Q: Do you provide customized packaging?
A: Yes, we can pack clips in small cartons, pallets, or steel drums according to your logistics requirements. Barcoding and labeling can also be added. -
Q: How long is the warranty period?
A: We offer a 12‑month warranty against manufacturing defects. Our long‑standing reputation in the industry ensures that any quality issues are addressed promptly. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 5000 pieces. Custom sizes may have a higher MOQ. Please contact our sales team for details.
