The invention discloses a anti-loosening bolt
assembly. The bolt
assembly comprises an anti-loosening bolt, an anti-loosening
gasket, a fastening nut and an anti-loosening
fastener, wherein the anti-loosening bolt further comprises a bolt head, a boss, a stud and an external thread, the boss is arranged at the bottom of the
screw head, the stud is arranged in the center of the bottom of the boss,the external thread is arranged on the stud, the anti-loosening
gasket, the fastening nut and the anti-loosening
fastener are sequentially arranged on an outer side of the stud from top to bottom, a through hole corresponding to the stud in size is formed in the center of the anti-loosening
gasket and the center of the fastening nut, and an internal thread is arranged on an inner wall of the fastening nut through hole. Compared with the prior art, the bolt
assembly is advantaged in that the bolt assembly is simple in structure, reasonable in design, and can effectively increase friction forcebetween the
fastener and the connecting piece, absorb vibration
impact, guarantee long-term stability of connection and have excellent anti-loosening performance.
