A rail screw spike, also called sleeper screw, rail screw or lag bolt, is a medium or large metal screw used to fasten a rail base plate or rail. Such spikes are always fastened into holes bored into the tie sleeper, sometimes together with imbedded plastic dowels.
Rail spike specifications
Q235 carbon steel offers good plasticity and toughness, suitable for general railway sleeper applications. 40Cr carbon steel is a high-strength alloy with superior tensile strength and wear resistance, ideal for heavy-duty and high-speed rail lines. Different materials can be selected according to environmental and operational requirements.
