Railroad spike, also know as rail spike. Railroad spikes are designed to maintain gauge between the running rails and also they are mean to secure the steel rail to the railroad tie. Rail spikes have various shapes serving for different functions. The materials for railroad spikes production can be carbon or stainless steel based on the requirement, and the surface of the spikes can be plain, black, hot dipped galvanized, or sherardized, etc.
