Tr22x149mm Special Head Screw Spike

Oct 23, 2025

Railway screw spikes are typically made from high-quality carbon steel or alloy steel to ensure durability and strength. The materials are often heat-treated to enhance hardness and toughness. In addition, to protect against corrosion, screw spikes may undergo surface treatments such as hot-dip galvanizing, electroplating, or dacromet coating.

The Tr22x149mm special head screw spike is a key fastener in railway track fastening systems, designed to secure rails firmly to sleepers, ensuring track stability under high-speed or heavy-load conditions. The special head design provides higher clamping force, enhancing the connection strength between rail, sleeper, and tie plate, effectively preventing lateral or longitudinal rail movement while reducing track wear and loosening.
