Rail-specific bolts and nuts are designed to securely fasten rails to sleepers or concrete foundations. They are typically made from carbon steel with surface hardness of 300–400 HB and tensile strength of 800–1000 MPa. Bolt diameters range from M16 to M36, with lengths from 60 to 250 mm. Threads are precision-made according to ISO or DIN standards, providing high shear and tensile load capacity. Surface treatment with hot-dip galvanization or epoxy coating enhances corrosion and wear resistance in railway environments.
Nuts are paired with flat, spring, or rubber washers to reduce vibration and loosening during train operation. The geometry ensures uniform transfer of axial and radial loads along the rail. Suitable for urban, industrial, freight, and passenger railway lines, these fasteners allow quick and safe installation. High mechanical strength increases rail durability and reduces maintenance costs.You can order and buy Rail special bolt and nut from Iran by contacting us through whatsaap and email.

Difference Between Rail-Specific Bolts and Nuts and Standard Bolts and Nuts in iran
Rail-specific bolts and nuts are made from high-strength steel with high hardness to withstand dynamic loads and impacts from trains or heavy machinery, while standard bolts are designed for light to medium loads. Rail bolt threads and diameters are precise and standardized to ensure rail stability and track safety, whereas standard bolts have more dimensional flexibility. Anti-rust coatings and surface hardness of rail bolts increase resistance to wear, moisture, and harsh weather. Using standard rail bolts and nuts ensures the longevity and safety of the railway structure.
