Products Description
In the laying of railway tracks, frog bolt is often used to connect sleepers and rails. It can ensure the stability of the track, reduce track deviation or shaking, and maintain the smoothness of train travel. In railway track engineering, frog bolt is used in conjunction with rail clamps to ensure that the rails are firmly fixed on the sleepers.
More product information
Square Head Frog Bolt are high-load railway connectors, which have strict requirements on materials and manufacturing processes. Commonly used materials are high-strength carbon steel (such as Q235, Q345), alloy steel (such as 35CrMo Frog Bolt), etc. These materials can achieve higher hardness and tensile strength after quenching and tempering.

Characteristics of rail bolts：
1. High strength and hardness:
rail bolts are made of high-strength steel and have extremely high strength and hardness after heat treatment process, and can withstand large loads and high pressure.
2. Excellent corrosion resistance:
rail bolts have good corrosion resistance and can operate stably for a long time in harsh environments, reducing maintenance costs.
Gnee's frog bolts are made of high-strength alloy steel and carbon steel, which have high strength, wear resistance and fatigue resistance, and are suitable for not only general railway lines, but also high-speed railways, heavy-duty railways, and other lines with high requirements for switch parts.
