About this item
- Complete Metric Threaded Inserts Set: Include 451 pieces in total, with M2 M2.5 M3 M4 M5 M6 knurled threaded inserts in 14 sizes, plus a soldering tip and an adapter. Work with heat, ultrasonic, or injection installation
- Secure Threaded Connections: Easily install these heat inserts into plastic parts or 3D-printed components. They create secure metal threads that ensure screws stay firmly in place for repeated use—while protecting the material from cracking or stripping
- Precision Threads & Knurled Grip: Inner high-precision threads provide secure fixation and stability. Expertly crafted knurls effectively increase friction for a firm grip, preventing twisting or slipping, and making installation easier and more efficient
- Reliable Brass Material: Made from strong, long-lasting brass, these heat set inserts deliver excellent thermal conductivity and resist deformation and corrosion. Ensure stable and secure installation, even under high temperatures up to 300 °C (572 °F)
- Wide Application: This nut insert kit is compatible with all thermoplastics, including PLA, ABS, PETG, PP, and more. Perfect for 3D printing, electronics and computer products, lighting, toys, furniture components, sports gear, and other DIY applications

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.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
