Self Trapping Track Screw Spikes For Railway And Mining Sleeper
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
