Product Details
✓【Package Content】- The package includes 220 high-quality metric threaded inserts for plastic heat-setting. With a large quantity available, it meets the needs for connecting numerous 3D printing accessories. The threaded brass inserts are approximately sized at M2.5x2.5x3.5, M2.5x4x3.5(mm). Please ensure the nut's size matches your plastic parts effectively.
✓【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】- 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.
✓【Easy to Use】- 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. With a common soldering iron, you can easily place them into the holes of 3D prints.
✓【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.
