Square Head / Rectangle Head Railway Sleeper Screw / Rail Screw Nail For Rail Track
Railroad screws 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
