Heat Treated Screw Spike for Railroad Fastening
Screw spikes consist of a head with a square or rectangular section with a round collar as well as a threaded part with a single thread of a considerable height and a considerable pitch.
Screw spikes are used to connect steel elements of a track structure with wooden or concrete sleepers. Depending on their type, screw spikes differ in terms of their length, pitch, and thread height; the mandrel diameter of the threaded part; and the dimensions of the collar part. One of the most commonly used types of screw spikes is square head screw spike.

Railway screw spikes provide a mechanical interlock that delivers more than twice the holding power of conventional hammered railway spikes.
Screw spikes are commonly used to fasten timber railway ties and sleepers, and they can also perform conjunction with plastic ferrules that have been casted into concrete ties/sleepers.
We can supply railway screw spike with various thread profiles, lengths, diameters and drive heads, which allow them to suit specific geographic requirements.
