About this item
- Common Specification: The thread insert set is consists of 100 insert nuts with M1.6 internal thread, length 3mm and an external diameter of 3mm. If other sizes of nuts are required, you can click on the drop down menu for more options.
- Stable & Long-Lasting Thread Inserts: Crafted from premium Copper materials, these threaded inserts boast outstanding corrosion resistance, thermal conductivity and durability. They exhibit remarkable resistance against breakage and deformation.
- Easy to Use: Knurled threaded inserts can be effortlessly embedded into blind or through holes with the heat of a soldering iron or ultrasonic method, providing a reliable and secure method of fastening parts in 3D printing projects.
- Secure Hold with Simple Application: The threaded nut has a knurled pattern on the outside, which is beautiful and also increases the friction between the nut and the hand, making it easier to rotate, significantly improving the torque and tensile strength. The round design of the head allows for good positioning and is not easy to skew, ensuring stable insertion.
- Wide Application: Threaded inserts are designed for all thermoplastics, including PLA, PETG, ABS, PPS, PP and others. Whether installing them in 3D printed objects, electrical molding machines, injection-molded plastic parts, automotive plastic casings, or laptop shells, their versatility ensures compatibility across a wide range of materials.

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.
