360 x Threaded Insert M2 M2.5 M3 M4 M5 M6, Bolatus Melting Nuts Brass with Soldering Iron Aid, Knurled Thread for Plastic Parts, Inserts 3D Printer Parts

Quality material: melting nuts and welding columns melting aid kit made of brass, with good thermal conductivity, not easy to deform. The surface is smooth and the thread is clear Strong and stable: Diagonal external thread design increases friction, ensures good stability and increases torque strength Wide application: the brass thread inserts are suitable for 3D printers, digital cameras, computers, plastic car parts, circuit board assembly, electronic products and most plastic firmware Easy to use: Install the thermal head with threaded insert on the welding rod and then insert it into the threaded hole of the threaded plug to heat it. After heating, press the melting thread into the plastic part Welding tool kit: welding rods with welding connectors (compatible with M2, M2.5, M3, M4, M5, M6, thread specifications) and adapters for quick replacement and effective adjustment to the melt
