ZWMSSLL M3 Heat-Set Threaded Inserts, M3x6x4.5mm | Brass for 3D Printing & Plastic Parts

• M3 Heat Set Threaded Inserts For Your 3D Printed Parts — The ZWMSSLL threaded insert are lead free,100 pieces M3x6x4.5mm Insert nuts.Different sizes of threaded inserts are individually packaged in thickened PE bags,Corresponding labels for the threaded inserts help you quickly find the desired type,Convenient use and storage，significantly boosting your work efficiency.
• High-Quality Threaded Inserts — Crafted from top-tier brass materials, these threaded inserts boast outstanding thermal conductivity, corrosion resistance, and durability. They exhibit remarkable resistance against breakage and deformation. Withstanding temperatures exceeding 300°C / 572°F, they easily endure the harsh heat generated during plastic thermal shaping processes.
• Precision Craftsmanship — The 45-degree angled knurling significantly enhances torque resistance and tensile strength, ensuring a stronger fastening. High-precision and clear threading ensures stability and reliability, preventing thread slippage during rotation. The embedded nuts feature guiding elements, eliminating the need for countersinking or recessing, making your work more convenient and efficient.
• Easy to Use — With a common soldering iron, you can easily place them into a blind or through hole of 3D prints.Brass threaded inserts can be installed into components of a 3D printer through heating or ultrasonic methods, or molded during the injection process. They are also suitable for circuit board assembly and the electronics field. The reusability of the insert nut is also possible by carefully removing them from the pressure part when they are no longer needed.
• Wide Application — These inserts are designed for use with all thermoplastics, including materials like PLA, PETG, ABS, PPS, PP, and others. Whether installing them in 3D printed objects, injection-molded plastic parts, automotive plastic casings, or laptop shells, these inserts offer reliable and durable solutions.

• Heat the Insert — Use a common soldering iron to heat the brass insert until it glows slightly, preparing for insertion into the plastic component.
• Insert into Plastic — Place the heated insert into the pre-drilled hole of your 3D print or molded part. Allow it to cool and set for a secure fit.
• Secure and Reuse — Ensure the insert is flush with the surface. Reuse is possible by carefully removing it with pliers when needed for repairs.
