ZWMSSLL 1/4"-20 Heat Set Threaded Inserts 30 Pieces Brass Knurled Nuts | Durable, Heat-Resistant Fasteners for 3D Printing & Plastic Parts

• 1/4"-20 Heat Set Threaded Inserts For Your 3D Printed Parts — The ZWMSSLL threaded insert are lead free,30 pieces 1/4"-20x6x8 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 / 585°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 soldering iron set to appropriate temperature (around 300°C). Hold the insert against the tip until it heats evenly, about 10 seconds.
• Position in Plastic — Insert into a pre-drilled hole in your plastic part. Hold steady for 3-5 seconds to allow the heat to embed the insert securely.
• Cool and Test — Allow the insert to cool for a few seconds. Test the fit by threading a bolt or screw to ensure proper engagement.
