<p>The present invention is to provide a self-locking bolt with a screw (3) along an outer circumferential surface of a shaft (2) by twisting at least two round rods (1) so as to prevent a bolt and a nut combined by vibration and temperature difference from being loosened. The self-locking bolt according to the present invention is characterized in excellently drawing a wedge action of locking prevention by giving variations on vibration and temperature transmission by constituting different material or different content of each round rod (1). The self-locking bolt of the present invention provides an advantage of significantly reducing the weight of a bolt body by forming a space on the outer circumferential surface of the shaft (2) due to characteristics of the bolt which is formed in the shape of of the shaft (2) by twisting at least two round rods (1).</p> |
