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/sleepers; however, they can also be used in conjunction with plastic ferrules that have been cast into concrete ties/sleepers.
Various thread profiles, lengths, diameters and drive heads are available to suit specific geographic requirements and Zhongyue can help with product specification and selection

4. Our advantage:
Our products are mainly made through hot forging.
The threads of rail screw spikes are made by hot rolling with special threading machines.
We produce metric threads, BS, BSW, TR thread, or round threads.
We also make rail fastenings for crane rail and elevator guide rail, along with other related products. We manufacture according to GB/TB (Chinese national standards and railway standards), AREA, UIC, BS, DIN, ASTM, and AS standards.
