The size of rail screw spikes directly affects track stability and load-bearing capacity. The length and diameter of the screw spike should be selected based on sleeper type, rail profile, and train load. Common dimensions for wooden sleeper screw spikes include 24×145mm, 24×150mm, and 24×160mm, typically with a diameter around 24mm, providing sufficient clamping force for high-speed and heavy-haul railways.

For concrete sleepers, screw spikes are usually used with plastic dowels, requiring slightly longer lengths to ensure firm anchorage. For instance, Ss series and DHS series screw spikes for concrete sleepers often have lengths of 160mm or 161mm to meet high-strength fastening requirements.
