After heating, the threaded insert is pressed into the part. </p><p>Then install the screws with the cooled nuts. Nuts can be easily inserted into plastic parts using ultrasound or a soldering iron.</p><p>*Knurled nuts are designed for thermoplastics. Threaded Insert Nuts are threaded connections for injection molding, circuit board assembly, electronics and most plastic fasteners such as PLA, PP, ABS, PETG.</p><p><br></p><p><strong><strong>Specifications:</strong></strong></p><p>Material: Brass</p><p>Number of pieces: 300 pieces</p><p><br></p><p><strong><strong>Package Included:</strong></strong></p><p>300PCS Threaded Inserts</p><p><br></p><p><strong>Note: </strong></p><p>Hot pressing process for nut inserts, please preheat the nuts before pressing process. Workers should wear insulating gloves during operation to avoid potential safety hazards during operation.</p><p><br></p><p><strong>How this works:</strong></p><p>Insert the threaded nut into the hole and heat the nut with a soldering iron. Brass has good thermal conductivity. After heating, the threaded inserts are pressed into the part. </p><p>The heated copper insert also conducts heat to the plastic part, softening the plastic around the hole and quickly pressing the product into the hole. </p><p>Then install the screws with the cooled nuts.</p><p><strong><strong><br></strong></strong></p><p><strong><strong><br></strong></strong></p><p><strong><strong><br></strong></strong><br></p><p><strong><br></strong><br></p>
