ABSTRACT:
A hobnail structure is composed of a connection rod and a cap installed on the connection rod, wherein the connection rod is a bolt, one end of which is provided with a ring of larger diameter with slant grooves having a same direction of deflection as that of threads of the aforementioned bolt located at rims of the ring. The cap is a cover, the bottom surface of which is provided with a slot hole, the diameter of which is smaller than that of the ring of the connection rod, and the slot hole is latched to the ring of the connection rod, so as to form a hobnail structure. Accordingly, the connection rod will not escape from the cap, resulting from an excessive exertion of a rotation force upon tightening, when the hobnail is screwed to a hole seat on a sole.
