Abstract: The present invention pertains to a dual protection cap for a bolt and a nut. The present invention relates to a protection cap for a bolt and a nut, which is open at one side and covers a bolt and a nut so as to separate the same from the outside, and comprises: an outer cap and an inner cap are respectively injection molded with synthetic resin; fitting grooves, which are formed on the inside of the outer cap at a uniform interval in a longitudinal direction, are fitted and coupled with protrusion pieces, which are formed to protrude from the outer periphery of the inner cap at a uniform interval in a longitudinal direction; and triangular protrusion pieces are formed on the end portion of each of fixing pieces, which radially protrude from the peripheral surface of the bottom surface in the inner cap.
