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 lock nut are staggered to each other, generating lifting tension, so as to achieve a perfect anti-loosening effect.

5. Anti-loose structure, through design improvement on the thread structure, without resorting to other external factors to obtain a self-locking function, so its applicability is wider than the above-mentioned methods, and the requirements for the environment are also relatively low.
