Production description
Anti loosening nuts and self tightening nuts are common types of fastening anti loosening nuts. Including mechanical anti loosening, riveting anti loosening, friction anti loosening, structural anti loosening, etc.
When the thread is tightened, the thread thread thread at the top of the bolt tightly enters the 30 ° wedge-shaped slope of the nut and is clamped, and the normal force generated on the wedge-shaped slope forms a 60 ° angle with the axis of the bolt, rather than a 30 ° angle. Therefore, the normal force generated when tightening the anti loosening nut is much greater than that of ordinary standard nuts, which has great anti loosening and anti vibration capabilities.
the 30 ° slope at the bottom of the nut thread can evenly distribute the locking force of the nut on all threads. Due to the uniform distribution of clamping force on each thread surface, the nut can effectively solve the problems of thread wear and shear deformation.
extensive use has shown that the locking force of the anti loosening nut remains unchanged after repeated tightening and disassembly, and the original locking effect can be maintained.
