Railway Sleeper Screw Overview
Railway sleeper screws, also known as railway screw spikes, are specialized fasteners used in railway track systems. Unlike ordinary rail spikes, railway screw spikes feature threads on the nail rod surface, which is why they are referred to as screw spikes. These screws are suitable for use with both wooden and concrete sleepers in railway tracks.
features of railway sleeper screws
Enhanced Pull-Out Force: Railway screw spikes offer a higher pull-out force compared to ordinary rail spikes, typically ranging from 0.5 to 1.0 times greater. This increased pull-out force helps to ensure the stability and security of the rail fastening system.
Reduced Thrust Resistance: While railway screw spikes provide enhanced pull-out force, they typically offer reduced thrust resistance, approximately 50% less than ordinary rail spikes. This characteristic allows for easier installation and removal of the spikes.
Usage in Turnouts and Frogs: Railway sleeper screws are commonly used in turnouts and frogs within railway track systems. Due to their design and characteristics, they are well-suited for applications where dismantling may be inconvenient and where track gauge adjustment is difficult.
