Features: 1) A of connectors, enabling the embedding of various M2 (common to M2.5), M3, , M5, M6 (1 or 4inch), and hot-melt nuts 2) Compatible with standard 936 universal soldering iron tips, convenient and practical (other models: FX-888D) 3) copper material, good thermal conductivity, end face contact, prevents the nut from skewing, and facilitates quick embedding of the nut into plastic parts 4) Compared with other similar indenter, our indenter is embedded at a short distance to avoid plastic parts after being pressed in. The head is not easy to damage the plastic parts and can be inserted into the plastic parts to a certain depth. 5) Using integrated design, the structure is stronger and integrated design, the components have stronger stress-bearing capacity.Note: Different countries have different voltages, so you need to choose a soldering iron tip that corresponds to the voltage and plug type. Name: Integrated hot melt nut Scope of application: Interchangeable with standard 936 universal soldering iron tip, used for M2 (common to M2.5), M3, , M5, M6 (1 or 4inch), and other hot-melt nuts or inserts, commonly used in 3D printers Print the hot-melt copper nut or embed the nut on the plastic Processing technology and color: CNC precision turning Material: copper colour: Gold Package Contents: 1 x Inlaid nut implant indenter kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm.
