Products Description

The lock nuts with External Tooth Lock Washer is a kind of nut widely used in machinery and other industries. Its working principle is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking under dynamic load will be reduced. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking.

M3-M16 Grade 4 Blue White Zinc Plated Serrated Flange Locknuts

The working principle of the nut is self-locking by the friction between the nut and the bolt. However, the reliability of this self-locking under dynamic load will be reduced. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. The lock nut is one of the anti-loosening measures.

The anti-loosening effect of the lock nut mainly depends on the interaction force between the nut and the bolt engaging thread. There are many ways to improve the interaction force between the meshing threads, such as the improvement of the thread structure of the Spiro nut, the nylon roughening of the nylon nut, and the surface treatment of the thread.

type

The first is to 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.

The second type is a special lock nut, which needs to be used with a lock washer. The special lock nut is not a hexagonal nut, but a middle 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 not only the focus of the tightening tool, but also the entry point of the locking washer.

The third type is to drill through threaded holes from the outer surface of the nut to the inner thread surface (usually two, distributed at 90 on the outer surface), which are used to screw in small diameter countersunk screws for the purpose of threading Apply a centripetal force to prevent the lock nut from loosening. A lock nut with better quality on the market is inlaid with a small copper piece on the inner surface of the nut that is consistent with the thread of the lock nut to prevent the radial jack screw from directly contacting the locked thread and damaging the latter. . This kind of lock nut has gradually begun to be applied in the occasion of the shaft end locking of rotating parts, such as the anti-loosening of the bearing at the mounting end of the ball screw.
