The Grade 4.8 Black Carbon Steel Lock Nut includes mechanical locking, riveting and punching locking, friction locking, structural locking, etc. It was first used in space aircrafts, and later extended to the automobile manufacturing industry. With the maturity of manufacturing technology and the reduction of cost, they are widely used in 3C, bicycles, skating and skiing equipment, furniture, sports equipment, medical equipment and other industries, comprehensively replacing the traditional stop washers, It fully shows the reliability of the fastening and locking function of the locking screw.
Three advantages of lock nut:
First, superior anti vibration performance: when the thread is tightened, the thread linearity of the top of the bolt tightly enters the 30 ° wedge inclined plane of the nut and is clamped, and the normal force exerted on the wedge inclined plane forms an angle of 60 ° with the axis of the bolt instead of 30 °. Therefore, the normal force generated when the lock nut is tightened is far greater than that of ordinary standard nuts, which has great anti loosening and anti vibration capacity.
Second, it has strong wear resistance and shear resistance: the 30 ° bevel of the nut thread bottom can make the nut locking force evenly distributed on the threads of all threads. Since the compression force on each thread surface is evenly distributed, the nut can better solve the problem of thread wear and shear deformation.
Third, good re-usability: extensive use shows that the locking force of the lock nut does not decrease after repeated fastening and disassembly, and the original locking effect can be maintained.
