SS Serie HDG Surface Railway Sleeper Screws 5.6 Grade For Railway Fastener
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.
