1x6-5/16” Hot dip galvanized BS Screw Spike

BS  Screw Spikes are fastening components specifically designed for railway systems in Commonwealth countries. Their unique dimensional specifications and protective requirements reflect the engineering principles of British railway standards. The 1x6-5/16 inch size precisely matches the installation needs of imperial concrete sleepers, with a 1-inch shank diameter providing sufficient load-bearing cross-section, and a 6-5/16 inch length carefully calculated to ensure adequate anchoring depth without causing structural damage from over-drilling.

The hot-dip galvanizing process delivers excellent corrosion protection for these spikes. During the rigorous process, the spikes undergo pickling, flux treatment, and immersion in molten zinc, forming a zinc-iron alloy coating with a thickness of 50–80 μm. This coating not only provides superior anti-corrosion performance but also exhibits strong adhesion to the base metal, allowing it to withstand mechanical friction during installation and maintain complete protection throughout long-term service.

Compared with other protective treatments, hot-dip galvanizing offers significant advantages for large fastening components. Its uniform coating ensures that every part of complex threaded profiles receives full protection, while the relatively high hardness of the zinc layer effectively resists damage from handling and installation. This makes it the preferred protective solution for coastal climates or areas with severe industrial pollution.
