Basic Structure & Features
Shape: Flat "dog head" shape (with a hook or raised edge) and a tapered shank for driving into wooden sleepers.
Function:
- The hooked head grips the rail base to prevent lateral movement.
- The shank anchors into the sleeper, providing longitudinal and vertical stability.
- Material: Typically made of Q235 carbon steel, often galvanized for rust prevention.
