Railway Bolts

Railway bolts are high-strength, specialized bolts used in railway track systems to connect rails to fasteners and rail-to-rail joints. On railway lines, railway bolts withstand the enormous impacts, vibrations, and tensile forces caused by temperature changes from passing trains. Thousands of railway bolts are needed per kilometer of railway, and their reliability directly affects train safety. Therefore, railway bolts have specific technical requirements, from material selection and heat treatment to surface corrosion protection.

Product Feature

High Impact Fatigue Resistance: Specifically designed for railway conditions, they can withstand millions of alternating loads without fatigue fracture.

Anti-Loosening Head Design: Semi-round or square heads, combined with specialized anti-loosening washers or spring washers, prevent loosening under strong vibrations.

Strict Dimensional Accuracy: Strict control over thread and shank dimensions ensures precise fit with gauge rods and fastener systems.

Easy Installation and Maintenance: Specialized wrenches or sockets allow for quick installation and removal, facilitating routine track maintenance and emergency repairs.
