What are the types of lock nuts?
1: Two identical nuts are used to screw on the same bolt, and a tightening torque is added between the two nuts to make the bolt connection reliable.
2: A special lock nut needs to be used together with a lock washer. The special lock nut is not a hexagon nut, but a middle round nut:.
3: A threaded hole is drilled from the outer surface of the nut to the inner thread surface for screwing in small-diameter countersunk screws. The purpose is to apply a centripetal force to the thread to prevent the lock nut from loosening .
4: The lock nut is composed of two parts, each part has a staggered cam, because the internal wedge design slope angle is greater than the bolt nut angle, this combination will be tightly bitten into a whole, when vibration occurs , The convex parts of the locknut are staggered to each other to generate lifting tension, so as to achieve a perfect anti-loose effect.
The fifth type is structural anti-loosening. Through the design improvement of the thread structure, it does not rely on other external factors to obtain its own locking function. Therefore, its applicability is wider than the above-mentioned methods, and the requirements for the environment are also relatively more. low. There are many types of locknuts, such as nylon nuts and flange nuts. In short, this kind of locknut is used to prevent loosening. Twist the nut onto the screw, screw, bolt, etc., until it will not come loose. They can be actively connected together, so that they are firm and stable to a high degree.
