In the intricate world of railway construction, the integrity of every component is crucial for the safety and efficiency of the entire system. Among these components, railway segment connecting bolts play a pivotal role. Longyu Track Materials, a leading manufacturer in the industry, specializes in producing these essential bolts, ensuring the highest standards of quality and reliability.

Introduction to Railway Segment Connecting Bolts

Railway segment connecting bolts, also known as rail joint bolts or fishplate bolts, are used to secure the sections of rail tracks together at the joints. These bolts are designed to withstand the heavy loads, vibrations, and environmental challenges typical in railway operations.

Specifications of Railway Segment Connecting Bolts

Material: The most common materials used for these bolts are high-strength steel alloys, known for their durability and resistance to wear and corrosion.

Size and Length: The size and length of the bolts vary depending on the type of rail and the specific requirements of the railway system. They are typically measured in millimeters or inches.

Thread Type: The bolts usually have a specific thread type, such as metric or imperial, to ensure a secure fit with the corresponding nuts and washers.

Strength Grade: The strength grade of the bolts is indicated by a numerical value, representing their minimum tensile strength. Higher grades are used for heavy-duty applications.

Coating: To enhance corrosion resistance, the bolts may be coated with protective materials like zinc or other anti-corrosive agents.

Types of Railway Segment Connecting Bolts

Hex Head Bolts: These are the most common type, featuring a hexagonal head that allows for easy tightening and loosening with standard tools.

Square Head Bolts: Used in applications where a flat bearing surface is required, square head bolts provide a large wrenching surface for secure tightening.

Button Head Bolts: With a low-profile, rounded head, these bolts are used in applications where space is limited or where a smooth surface is desired to reduce the risk of injury or snagging.

Countersunk Head Bolts: These bolts have a tapered head that sits flush with the surface of the rail when installed, reducing the risk of tripping or snagging.

Applications of Railway Segment Connecting Bolts

Railway segment connecting bolts are used in various applications, including:

Rail Joints: Connecting sections of rail at the joints to ensure continuity and stability of the track.

Switches and Crossings: Securing the movable components in switches and crossings, which are critical for directing trains onto different tracks.

Bridge and Tunnel Connections: Attaching rails to the supporting structures in bridges and tunnels to maintain alignment and stability.

Signal and Communication Systems: Mounting equipment for signal and communication systems along the railway track.
