Button head diamond neck track bolts are one of the most important fasteners in the railway fastening system. They are used to connect steel rails and fishplates, thereby securing the rails to the sleepers. Button head diamond neck track bolts are widely used in railways to ensure the safety and stability of the railway. Button head diamond neck track bolts are typically made of high-strength steel, such as Q235, C35, and 16Mn, and are widely applied in heavy-duty railway transportation, urban rail transit, and mining railways. Suitable for various track types and sleeper materials, such as wood, concrete, and composite sleepers. Button head diamond neck track bolts consist of three parts: the bolt head, the bolt neck, and the bolt shank. The head is round-shaped, effectively reducing pressure concentration and lowering the risk of breakage; the neck is diamond-shaped, which enhances the contact area between the bolt and the rail, preventing the bolt from slipping.
As a technology-leading track bolts supplier, AGICO provides button-head diamond neck track bolts with high quality, excellent wear resistance, and corrosion resistance, ensuring compliance with all relevant standards. They can also produce bolts of different specifications according to customer requirements. AGICO also manufactures supporting railway fasteners, such as rail fishplates, rail nuts, rail washers, and more.

Advantages of Button Head Diamond Neck Track Bolts
High Wear Resistance
The head, neck, and shank of button head diamond neck track bolts are made of high-strength steel, which undergoes strict material selection and testing, possessing extremely high tensile strength. The manufacturing process uses heat treatment to improve the durability of the bolts. The surface treatment uses zinc plating, HDG, and plain oil, which enhances the corrosion resistance of button-head diamond neck track bolts, allowing them to be used for a long time in various climates.
Superior Design
The smooth shape of the head of the button head diamond neck track bolts provides a larger contact area, evenly distributing pressure and preventing the bolts from loosening. Additionally, the smooth surface reduces wear on other track components, extending the lifespan of the bolts. The diamond-shaped neck design offers higher embedding force, preventing track displacement and deformation.
Wide Application
Button head diamond neck track bolts are suitable for various types of railways, such as freight railways, passenger railways, high-speed railways, and urban rail transit systems. Additionally, their design and materials are suitable for various types of sleepers, such as wood, concrete, and composite sleepers. Besides being used in railway systems, they can also be applied in mines, ports, and other projects that require component connections.
Easy Installation and Maintenance
The design of button head diamond neck track bolts allows them to be easily and quickly inserted into the rail holes and fixed with a wrench. This reduces construction time and improves work efficiency. The diamond-shaped neck design reduces the possibility of loosening, decreasing maintenance frequency and costs.
