DIN 5526:1999 Headed Pin

DIN 5526:1999 Headed Pin adopts a headed pin design for railway vehicles to meet the needs of pin connections needing dependable retention, easy inspection, and resistance to vehicle operating vibration.

The headed end assists stopping and removal, while the shank provides locating or shear function; with cotter pins, washers, or retainers it forms a complete safety assembly. Its advantages lie in a clear installation method, well-defined load path, and good adaptability across different materials and installation spaces.

This product is suitable for railway vehicles, bogie accessories, brake mechanisms, connecting rods, and rail equipment maintenance. Material strength, surface protection, and matching retaining parts can be adjusted for the final application, balancing cost control, corrosion protection, and assembly consistency.
