What is the rail bolt?
Rail bolts, also known as rail bolts or rail anchor bolts, are used to secure rails or base plates to sleepers. Rail bolts are bolts that are inserted into holes in the sleepers and have a funnel nut that bites into the underside of the sleeper.
Rail bolts are a type of high-strength, high-corrosion-resistant fasteners that are widely used in railway tracks, bridges, building steel structures and other fields. They are uniquely designed and made of high-quality steel. After heat treatment, quenching, tempering and other processes, they have high strength, high hardness and good wear resistance. Rail bolts also have good corrosion resistance and can operate stably for a long time in harsh environments.

Application of rail bolts
1. Railway tracks: Rail bolts play a vital role in the connection of railway tracks. They fix the tracks to the ballast, ensuring the precise alignment and stability of the tracks, thereby ensuring the safety and smoothness of train travel.
2. Bridge construction: In bridge construction, rail bolts are used to connect various parts of the bridge, such as steel beams, bridge piers, etc. Their high strength and corrosion resistance ensure the stability and safety of the bridge structure.
3. Building steel structure: In building steel structure, rail bolts are used to connect steel components, such as steel beams, steel columns, etc., and their excellent performance ensures the stability and safety of the building structure.
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. Good wear resistance: rail bolts need to withstand the heavy pressure and friction of trains in daily use, and their excellent wear resistance can ensure long-term stable operation.
3. Excellent corrosion resistance: rail bolts have good corrosion resistance and can operate stably for a long time in harsh environments, reducing maintenance costs.
4. Precision manufacturing and strict quality control: The manufacturing process of rail bolts strictly abides by industry standards, adopts precise manufacturing processes and strict quality control to ensure the quality and performance of the products.
With the continuous development of industrial technology, rail bolts will be used in more fields, providing strong support for the sustainable development of all walks of life.
