The external surface of the hot insert has a high-precision, clear thread knurling design. After the copper insert is hot-injected into the plastic part, the outer diameter of the product is embossed, which forms a certain friction and bite force with the product after molding, ensuring a high fastening force, making your work more convenient and efficient. How to use it? Pre-drill plastic, heat insert to Tm temp with iron. Align, press firmly, apply pressure for insertion. Cool and solidify. Knurled nuts secure various plastics โ€“ PLA, PETG, ABS, PP. What should I notice? Manual measurement may cause a 1-2mm size error. There will be color differences due to different displays. Please refer to the actual product received

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
