Railway spiral spikes are special spikes used to fix railway tracks. Their main function is to firmly fix the rails on the railway sleepers and ensure the stability and safety of the railway. According to national standards, railway spiral spikes should meet the following requirements:

1. Material:

The material of railway spiral spikes should be carbon steel or alloy steel, and its chemical composition should meet the requirements specified in national standards.

2. Specifications:

The specifications of railway spiral spikes should meet the requirements specified in national standards, including thread size, thread angle, thread length.
Thread height, thread cross-sectional shape and other indicators.

3. Performance:

The performance of railway spiral spikes should meet the requirements specified in national standards, including pull-out strength, torque coefficient, wear resistance, corrosion resistance and other indicators.

4. Surface treatment:

The surface of railway spiral spikes should be treated with anti-corrosion to improve their anti-oxidation and corrosion resistance.

5. Marking:

Railway spiral spikes should be engraved with relevant markings on their surfaces, including information such as manufacturer, production batch number, specification model and so on.

The above are the main contents of the railway spiral spike standard. Railway-related departments and enterprises should produce and use them in accordance with this standard to ensure the stability and safety of the railway.
