【Convenient M3 Threaded Insert Kit】This m3 heat set inserts includes 130 x M3x5.7 brass inserts. Each heat set insert featuring an M3 internal thread and a 5.7 mm length. Designed for both heat and ultrasonic embedding methods, these nuts provide a reliable threading solution for your 3D printing projects.
【Precision Craftsmanship Fixed Hold】 Featuring high-precision and clear threading , M3 threaded inserts for plastic it firmly in the pressure part, prevent slippage while significantly improving torque resistance and tensile strength. The 45-degree angled knurling significantly enhances a balanced high tightening and loosening torque, as well as a high tightening force, ensuring effortless and secure installation every time.
【Premium Brass Material】M3 inserts are made from high-quality brass, these threaded inserts for plastic deliver excellent thermal conductivity, corrosion resistance, and long-lasting durability. They resist breakage and deformation, even under extreme conditions—withstanding temperatures over 300°C / 572°F, making them ideal for heat-based installation in 3D printing and plastic molding.
【Easy to use】: M3 brass threaded inserts for 3d printing can be installed into components of a 3D printer through heating or ultrasonic methods, or molded during the injection process, even multiple assembly/disassembly cycles. The brass inserts 3d printing are also suitable for circuit board assembly and the electronics field.
【M3 Heat Inserts Wide Applications】 Ideal for a wide range of 3D printing filaments, including PLA, PETG, ABS, PPS, PP, and more. Once the surrounding plastic cools and solidifies, the knurled brass sleeve forms a permanent, rock-solid anchor within the part.
