ZhongYue Self Trapping Screw Spikes Track for railway and mining
sleeper
1. Introduce
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
