Anti-loosening nuts and self-tightening nuts are common fastening anti-loosening nuts. Including mechanical anti-loosening, riveting anti-loosening, friction anti-loosening, structural anti-loosening, etc.

Three advantages of lock nuts:

First, superior anti-vibration performance: when the thread is tightened, the thread linearity of the top thread of the bolt firmly enters the 30 ° wedge-shaped inclined surface of the nut and is clamped, and the normal force generated by applying it to the wedge-shaped inclined surface is the same as that of the bolt. The axis is at an angle of 60 ° instead of 30 °. Therefore, the normal force generated when the anti-loosening nut is tightened is much greater than that of the 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 bottom of the nut thread can make the locking force of the nut evenly distributed on the threads of all teeth. Since the pressing force on the thread surface of each tooth is evenly distributed, the nut can better solve the problem of thread wear and shear deformation.

Third, the reuse performance is good: a large number of uses show that the locking force of the anti-loose nut is still not reduced after repeated tightening and disassembly, and the original locking effect can be maintained.
