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. BulletPoint3 : 【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. BulletPoint4 : 【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. BulletPoint5 : 【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.
