Provides good mechanical properties with increased corrosion and heat resistance The knurled insert nut has a guide, so no countersink is required. The surface is smooth, firm and even, and easy to install. It can be installed into a plastic matrix by ultrasound or heat during the injection molding process. Can be widely used in 3D printing injection molding to achieve tight fixation. Because the outer diameter of the insert is embossed, it forms certain friction and bites force with the brass insert after molding, which can be fixed on the inside and will not fall off. Has a certain torsion and tension.
