Product Introduction
Ss35 Rail screw spike, also called Ss35 sleeper screw, Ss35 rail screw or Ss35 lag bolt, is a medium or large metal screw used to fasten a rail base plate or rail. Ss35 rail screw spike provides a mechanical interlock that delivers more than twice the holding power of conventional hammered rail spikes. It is an important fastener of W14 Rail Fastening System. Ss35 Rail Spike is used to fix the tie plate or fasten the rail to the concrete sleeper with the help of Sdu25 plastic dowel. It has a very similar one called DHS35 Sleeper Screw Spike. The difference between Ss35 Screw Spike and DHS35 Screw Spike is the shape of the head. Ss35 Screw Spike has a square head and the other has a tapered head.
The Ss35 screw features a zinc plated finish, providing enhanced corrosion resistance for coastal, humid, or standard industrial railway environments. The zinc layer prevents surface oxidation, extends service life, and ensures long-term fastening performance.
