ISO7040 Stainless Steel SS316 304 Grade 5 / 8/ 10 Lock Nuts
Lock the outer joint of the wire or other fittings. The working principle of the nut is to use the friction between the nut and the bolt to self-lock. However, the reliability of this self-locking in dynamic loads is reduced. In some important cases, we will take some anti-loose measures to ensure the reliability of the nut locking. Lock nuts are one of the anti-loose measures. The anti-loose effect of the lock nut mainly depends on the interaction force between the nut and the bolt engagement thread. At present, there are many ways to improve the interaction force between the meshing threads, such as the improved thread structure of the Shibong nut, the nylon roughening of the nylon nut, and the surface treatment of the thread.
