1. Good repetitive 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.
　

2. 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.

3. Excellent anti-vibration performance: When the thread is tightened, the crest thread of the bolt tightly enters the 30° wedge-shaped inclined surface of the nut to be clamped, and the normal force exerted on the wedge-shaped inclined surface is related to the axis of the bolt. The angle is 60° instead of 30°. Therefore, the normal force generated when the nut is tightened is much greater than that of the ordinary standard nut, which has great anti-loose and anti-vibration ability.
