Bolt and nut fasteners are widely used fasteners, which can be used in mechanical products as well as daily craft industrial products, such as plastic packaging boxes, plastic packaging boxes, paper packaging boxes, paper packaging boxes, etc. . When bolt and nut fasteners are used in daily craft industrial products, the requirements for the degree of tightening are generally low, but they are required to be easy to install and use. When assembling the existing bolt and nut fasteners, it is generally necessary to manually twist the bolt or the nut several times until the two are tightened, which takes time and causes inconvenience in daily life. Lower, it is manifested as an increase in labor costs. SUMMARY OF THE INVENTION The main purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a bolt and nut fastener that is easy to install in view of the above-mentioned deficiencies of the prior art. The two are assembled and fastened, which is convenient to use.
