Functions And Features of Metal Railway Screw Spikes

Metal railway screw spike, or rail screw, is a type of rail fastener first introduced in 1860 in France (French tire-fond), and then became common in continental Europe. And now metal railway screw spike is one of the most popular rigid rail fixation items. Metal railway screw spike is a large metal screw used to fix rail tie plates or fasten steel rails. Metal railway screw spikes are fixed into a hole bored in the sleeper. Metal railway screw spikes can be various in thread profiles, lengths, diameters and drive heads based on specific geographic requirements. Metal railway screw spike costs more to manufacture than the dog spike or dog nail but has the advantage of greater fixing power; approximately twice that of a dog spike and can be used in combination with spring washers.

Having a head and a threaded shank portion, the upper surface of said head being provided with a relatively slender upstanding malleable straight-sided projection extending about of an inch from the upper surface of said head and which will crush-flatten over the adjacent upper surface of the head, when the metal railway screw spike is maul-driven instead of screw driven, providing a visible tell-tale upon the head of the spike.
