Incorrect selection of fasteners is a problem often found when performing industrial production. The following are frequent occurrences of such problems.

The selection of a thread locking method with excellent anti-loosening effect is the root of the problem. This approach can increase the preload of the bolt, its friction has also been increased, of course, the loosening effect can also be improved.

(1) Fasteners subjected to axial force, the threads are destroyed and the bolts are pulled off. (2)Fasteners subject to radial force, the bolt is sheared off, and the bolt hole is beaten into an ellipse.
