Frog Bolt

Ordinary bolts cannot meet the requirements of turnouts for strength, stability and reliability, while special turnout bolts are specially designed and manufactured to better adapt to the stress characteristics of turnouts.

The high-quality railway frog bolts produced by Gnee are precisely designed, and the size and thread specifications can accurately match the bolt holes of turnout components. According to the models, specifications and structural characteristics of different turnouts, accurate size and installation parameters are provided to ensure the installation quality and performance of turnouts.

Advantages of Frog Bolt

High Strength and Stability:

• Gnee frog bolts are made of high-strength alloy steel and other materials, such as 35CrMo, 42CrMo, etc., with high tensile strength and yield strength, and can withstand the huge pressure, impact and shear force generated when the train passes through the frog

Good Corrosion Resistance:

• Considering the use environment of railway turnouts, Gnee’s frog bolts are generally subjected to special surface treatments, such as hot-dip galvanizing, Dacromet treatment, etc., to make them have good corrosion resistance, which can effectively prevent the bolts from rusting and corrosion, and reduce the replacement and maintenance costs caused by bolt corrosion.

High precision and adaptability:

• The manufacturing process of our frog bolts has high requirements for dimensional accuracy and thread accuracy, ensuring that the bolts and the bolt holes of the frog components fit tightly, and there will be no loosening or excessive gaps after installation;

Good anti-loosening performance:

• Gnee’s frog bolts adopt a special anti-loosening design, such as double nuts, spring washers, self-locking nuts and other anti-loosening devices, which can effectively prevent the bolts from loosening under the vibration of the train and ensure the reliability of the frog connection.
