Low Carbon Steel Black Oxide Track Spike Fastening Wooden Sleeper Ss-EN10025
General Intoduction of Track Spike
The spikes used to fasten T-shaped railroad track to wooden ties have an L-shaped head and a square shank. The bottom of the head is sloped to match the slope of the flange of a rail. The tip is wedge-shaped, not pointed. The wedge is driven into the tie across the grain, that is, parallel to the track.
Its square cross section gives a railroad spike much higher holding strength than a fastener having the same amount of metal but a circular cross section has; roughly speaking, about 50% more. A spike with the wedge driven across the grain will have about twice as much holding power as one driven with the grain. Early experiments showed that pulling out a 9/16″ × 9/16″ spike driven 4¼ inches into dry cedar required on average a force of 857 pounds. In seasoned oak, another experimenter needed 4281 pounds.
Current standards for track spikes define two grades: 1 (soft) and 2 (high carbon). The stronger high carbon spikes must be marked “HC”.
