10.9 Grade 40Cr Steel Oxide Black Screw Spike Railway Spike Insert Plastic Dowel Railway Fasteners


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.
