Oct 21, 2025
Screw spikes are used to connect steel elements of a track structure with wooden or concrete sleepers. It is also called: chair screw spike, sleeper screw, collar bolt, lag bolt. Depending on their type, screw spikes differ in terms of their length, pitch, and thread height; the mandrel diameter of the threaded part; and the dimensions of the collar part.

The rail sleeper screw spikes are used to fasten the sole plate and ribbed base plates to wooden sleepers or together with plastic dowel and flat or spring washers, to fix the tie plate or rail clip on the concrete sleepers, to make sure the steel rail stable on the right position.
The 24×150mm Railway Ss8 Sleeper Screw Spike is a critical fastening component in railway track systems, designed to securely fix rails to sleepers, ensuring track gauge accuracy and the overall structural stability of the track. The Ss8 screw spike features a threaded design, providing high clamping force and excellent pull-out resistance, effectively resisting longitudinal and lateral vibrations generated during train operations. It is an indispensable fastening solution for high-speed railways, heavy-haul freight lines, and urban transit track construction.
