Anti-loosening nut is a kind of nut with high anti-loosening performance, which can work normally in extreme environments.
Generally speaking, locknuts have three advantages. First, superior vibration resistance: When the thread is tightened, the thread of the bolt's crest is tightly entered into the 30° wedge-shaped inclined surface of the nut and is clamped and applied to the wedge-shaped inclined surface The normal force generated is at an angle of 60° with the axis of the bolt instead of 30°. Therefore, the normal force generated when the nut is tightened is much greater than that of an ordinary standard nut, which has great anti-loosening and anti-vibration ability.
Second, strong wear resistance and shear resistance: the 30° inclined surface of the nut thread bottom can make the nut locking force evenly distributed on all the threads of each tooth. Since the compression force on each thread surface is evenly distributed, the nut It can better solve the problems of thread wear and shear deformation.
Third, good reusability performance: extensive use shows that after repeated tightening and disassembly of the nut, its locking force is still not reduced, and the original locking effect can be maintained.
