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.

When selecting screw spikes, it is important to ensure that their dimensions and specifications meet the project requirements. Different models of rail fastening spikes are suitable for different types of sleepers, and improper selection may affect the fastening performance.
The installation process is equally critical-ensuring that the rail screw spike is driven to an appropriate depth, avoiding over-tightening or insufficient insertion, as either can lead to track deformation or premature spike failure.
