The real cause of damage to threaded fasteners

After the threaded fasteners are loosened, huge kinetic energy mv2 is generated. This huge kinetic energy directly acts on the fasteners and equipment, causing damage to the fasteners. After the fasteners are damaged, the equipment cannot work under normal conditions, which further leads to Equipment damage.

For fasteners subjected to axial force, the thread is broken and the bolt is broken.

For fasteners subjected to radial force, the bolts are cut and the bolt holes are punched into an oval.

Selecting the thread anti-loosening method with excellent anti-loosening effect is the fundamental solution to the problem: (Guide: Tips on the use of screws and nuts)

At present, the most advanced and effective anti-loosening method is Down's threaded fastener anti-loosening method.

Down's thread has the characteristics of both left-hand and right-hand threads. It can not only cooperate with left-hand thread, but also with right-hand thread.

Two kinds of nuts with different rotation directions are used for connection. The nut on the working support surface is called a tightening nut, and the nut on the non-supporting surface is called a lock nut. When using, pre-tighten the tightening nut first, and then pre-tighten the lock nut.

In the case of vibration and shock, the tightening nut will tend to loosen. However, since the loosening direction of the tightening nut is the tightening direction of the tightening nut, the tightening of the tightening nut just prevents the tightening of the nut. Loosening, resulting in the fastening nut cannot be loosened.
