The screw spike, also called rail screw, it can be used to fasten the ribbed base plates and sole plates to wood sleepers. It can be used to fasten the SKL Clip to rails and will obtain high clamping force. It has better fixing power than rail spike or dog spike, which lead to it's widely using in many fastening system.

Stainless steel screws are widely used in various engineering applications for their corrosion resistance, but they are not always stronger than regular carbon steel screws. Ordinary screws, such as railway Grade 4.6 or 5.6 carbon steel sleeper screws, are heat-treated and surface-finished to provide superior tensile and shear strength, making them more suitable for high-load and heavy-haul railway conditions.

The advantage of stainless steel screws lies in their resistance to oxidation and corrosion, making them ideal for coastal, humid, or chemically aggressive environments. However, under conditions of high-speed train operation, heavy freight, or frequent vibrations, their hardness and fatigue resistance may be lower than that of reinforced carbon steel screws, which is why conventional steel screws remain the mainstream choice in the railway industry.
