Black ISO Screws For Railway Sleepers Railroad Coach Screw Spike M24
1. Introduce:
Railroad screws 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
