    Pole barn spike

    Anyone know what a "pole barn spike" is? Got a 200'x75' pole barn, and the headers each side of the column are fastened with 4" pole barn spikes (no quantity given) and 5-5/16" structural screws. I doubt thats going to work for a 75' span, but would like to see how many "spikes" it would need.
