Rail Screw Spike Track Spike

Rail Screw Spike Track Spike

The Sleeper Screw Spike is a robust fastening solution specifically designed for railroad track installations. Made from high-strength steel, it features a distinctive square head that provides excellent torque application and prevents slippage during installation. The shank of the spike is fully or partially threaded, allowing it to be securely screwed into pre-drilled holes in wooden or concrete sleepers. This design ensures stability and durability under the heavy loads and dynamic forces experienced by rail traffic. The square head also offers a larger surface area for tools, making it easier to tighten or loosen compared to traditional hexagonal or round heads.
