A nut provided by Yueluo. The nut is in the shape of a casing and is provided with a threaded section. One end of the threaded section is provided with a protrusion on the wall of the hole. The nominal size of the segment or the distance from the rear end of the lug to the hole core in the screw-in direction is smaller than the nominal size of the threaded segment.

1. Other names: root nut, anti-loosening nut, nut. 2. Purpose: To lock the outer joint of the through wire or other pipe fittings. The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking is reduced under dynamic loads. 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 thread of the bolt. There are many ways to improve the interaction force between meshing threads, such as structural improvement of nut threads, nylon roughening of nylon nuts, and surface treatment of threads.

The nut is based on the reaction force principle of the inner hexagonal cone of the clamping part and the outer hexagonal cone of the locking part. The higher the pressure, the tighter the lock, so that the bolt can achieve the purpose of self-locking and tightening. The existing bolts rely on multiple nuts against each other to prevent loosening. This method cannot be completely locked, and the bolts are easily loosened when subjected to huge pressure and vibration, which hides potential safety hazards;

T-bolts are often used in conjunction with flange nuts, which are standard supporting connectors when installing corner fittings, and can be automatically positioned and locked during the installation process. At present, in the welding process of T-bolts, there is often a method of manual welding. Using such a method, the manufacturing cycle is long, the labor intensity is high, the production efficiency is low, and the welding quality is difficult to guarantee.
