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, popularly used for rails with wooden sleepers, especially in America and Canada.
The screw spikes are typically made of high-strength carbon steel or alloy steel, such as Q235, 35#, or 45#, offering excellent tensile strength and wear resistance. They are suitable for high-speed rail, heavy-duty freight lines, and urban rail transit systems.
