Screw spikes are similar to drive spikes but have a larger, more prominent thread. This makes them ideal for use in areas where there is a lot of vibration and movement. Screw spikes are typically used in conjunction with special plates, known as base plates, which are used to distribute the weight of the rail over a larger area.

The Ss8 Fe6 24Ø×165mm Railway Sleeper Screw Spike is part of the rail screw spike series, which serves as a primary fastening component connecting rails to sleepers in railway track systems. Rail screw spikes form a secure mechanical interlock through their threaded shank, providing excellent pull-out resistance, vibration stability, and long-term durability.
The Ss series sleeper screw spikes produced by GNEE RAIL (including models Ss1 to Ss36) are widely used in mainline railways, metro systems, heavy-duty freight lines, and industrial tracks. The Ss8 model, made of Fe6 steel, features a 24mm thread diameter and 165mm length, suitable for various sleeper structures and fastening systems.
