In the precision system of industrial manufacturing, insert nuts, as key components for connecting plastics and metals, play an irreplaceable role in various industrial scenarios by virtue of their diverse installation methods and significant advantages. These small parts with knurling on the outside and internal threads, through scientific design and precise installation, endow products with stab
