1. Use two identical nuts to screw on the same bolt, and add a tightening torque between the two nuts to make the bolt connection reliable.
2. The special
fastener nut needs to be used together with a kind of anti-loose washer. The special lock nut is not a hexagonal nut, but a round nut. There are 3, 4, 6 or 8 notches on the circumference of the nut (depending on the size of the nut and the product series of the manufacturer). Several notches are both the focal point of the tightening tool and the snap-in of the lock washer bayonet.
3. A threaded hole is drilled from the outer surface of the nuts to the inner thread surface, which is used to screw in a small diameter countersunk head screw. The purpose is to apply a centripetal force to the thread to prevent the lock nut from loosening.
4. The
fastener nuts are composed of two parts, each part has staggered cams. Since the slope angle of the internal wedge design is greater than the nut angle of the bolt, the combination will be tightly integrated into a whole. When vibration occurs,the DISC-LOCK anti-loosening nuts are staggered with each other, the lifting tension is generated, so as to achieve the anti-loosening effect.
5. By improving the design of the thread structure, a self-locking function can be obtained without relying on other external factors, so its applicability is wider than the above types. There are many types of lock nuts, such as nylon nuts, flange nuts, etc. In a word, this kind of fastener nuts plays a role in preventing loosening.
