Rail Screw Spike Dimension
The dimensions of rail screw spikes can vary depending on factors such as the type of rail, sleeper material, and specific application requirements. However, here are some typical dimensions for rail screw spikes used in standard railway construction:
Length: Generally, rail screw spikes range from around 5 inches (127 mm) to 9 inches (229 mm) in length, with variations depending on the specific railway standards and requirements.
Diameter: The diameter of the threaded portion of the spike typically ranges from about 3/4 inch (19 mm) to 1 inch (25 mm).
Thread Pitch: The thread pitch, or the distance between adjacent threads, is usually standardized to ensure compatibility with the corresponding nuts or fastening components.
Head Size: The head of the spike is usually larger than the threaded portion to provide a surface for driving the spike into the sleeper and to ensure proper rail fixation. The head diameter can vary but is typically around 1.5 to 2 times the diameter of the threaded portion.
