<p>The present invention relates to a cap for preventing theft of a bolt and a nut, wherein especially in the state in which a spiral axis of a bolt penetrates structures when a nut is spirally connected to the spiral axis to combine the structures through the tightening force of the bolt and the nut, by maintaining a state in which the outside of the nut is covered with a cap, theft of the nut can be prevented. The cap is characterized by comprising: a cap in which the bottom side is opened for covering the nut when the nut is connected spirally to the spiral axis of the bolt penetrating the structures; and a protective cap having a nut-fixing member being able to hold the outside of the nut in a state in which the outside of the nut can be rotated arbitrarily within the cap.</p> |
