ASTM Standard Hot Dip Galvanized Railway Sleeper Fixing Screws /
Rail Road Spikes
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.
