Oxide Black 8.8 Grade DIN Standard Railway Screw Spike High Hardness
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 Suyu can help with product specification and selection.
