GB/T 889.2 Lockable Nut

GB/T 889.2 lockable nut has the following 3 advantages:

First, excellent anti-vibration performance: when the thread is tightened, the
crest thread of the lockable nut and bolt tightly enters the 30° wedge-shaped
slope of the nut and is clamped, and the normal force exerted on the wedge-
shaped slope is the same as the bolt's normal force. The axis forms an included
angle of 60° instead of 30°. Therefore, the normal force generated when the
anti-loose nut is tightened is much larger than that of the ordinary standard
lock nut screw, and it has a great anti-loose and anti-vibration ability.

Second, the wear resistance and shear resistance are strong: the 30° slope of
the nut thread bottom can make the lockable nut locking force evenly
distributed on the threads of all the teeth. Lock nut pack can better solve the
problems of thread wear and shear deformation.

Third, the repeated use performance is good: a lot of use shows that the
locking force of the locking nuts and bolts will not decrease after repeated
tightening and dismantling, and the original locking effect can be maintained.
