• The Kit has 420Pcs Threaded Inserts,includes M2 M3 M4 M5,4 size of M2 has 30 pieces,total 120pcs;4 size of M3 has 30 pieces,total 120pcs;4 size of M3 has 30 pieces,total 120pcs;3 size of M5 has 20 pieces,total 60pcs;These heatset inserts can be widely used on the injection moulding for tightly fixing. Can be installed by ultrasonic or heat into thread tapered hole, or molded in during injection. Also apply to circuit board assembly and in the field of electronics.
• High-precision and clear threading ensures stability and reliability, preventing thread slippage during rotation. The 45-degree angled knurling significantly enhances torque resistance and tensile strength, ensuring a stronger fastening. The embedded nuts feature guiding elements, eliminating the need for countersinking or recessing, making your work more convenient and efficient.
• 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.
• Easy to use: The brass threaded insert can be installed into the part of the 3d printer by heating or ultrasonic. Due to the geometry of the threaded sleeve, it holds firmly in the pressure part. The opposing spiral knurled nut ensures a high balance of tightening and loosening torque. Through the guide, insertion has been greatly simplified.
• Widely Application: Metric knurled nuts assortment kit can be embedded in a wide range of plastics, whether you're reinforcing 3D printed parts or assembling plastic components, this assortment gives you a wide variety of threaded inserts to choose from. Various sizes ensure compatibility with different bore and thread sizes, enabling a variety of applications.
• Convenient use and storage,stored in reinforced compartmentalized boxes, all components are segregated to prevent mixing during transportation. Corresponding labels and compartments for the threaded inserts help you quickly find the desired type, significantly boosting your work efficiency.

• Prepare the Insert & Heating Tool — Select the appropriate size, heat the soldering iron tip to 350°C / 662°F, and ensure the insert is clean for optimal heat transfer.
• Insert into Plastic Part — Position the insert in the pre-drilled hole, press the heated tip against the knurled surface, and hold until the plastic melts around it.
• Cool & Secure — Allow the insert to cool for a few seconds, then check for firm embedment. The insert now provides a durable metal thread for fasteners.
