In order to solve the problems existing in the prior art, Yueluo Company provides a fastener that prevents the nut from falling off. After the nut is installed in place, a locking strip can be inserted into the groove of the bolt to lock the nut, so that the nut can be locked. It cannot be loosened to prevent the nut from falling off. If the nut needs to be removed, the nut can be removed normally after removing the locking strip.

Washers are accessories used between the nut and the connecting piece to disperse the pressure of the nut on the connected piece, thereby protecting the connected piece. The general gasket is a flat gasket, which is easy to loosen after long-term use, and the stability is not high. There are also some elastic washers, which have poor elastic stability and short service life.
