Packing list: 1PC HS-02A/C245 hot melt nut insert kit Product information: 1. Product name:HS-02A/C245 hot melt nut insert kit 2. Product scope of application: This product uses soldering iron adapted to HS-02A/C245, and is used for M2 (common to M2.5), M3, M4, M5, M6 (1/4"), Hot-melt nuts or inserts such as M8 are often used for hot-melt copper nuts printed on 3D printers or to embed nuts on plastics. 3. Processing technology and color: CNC precision turning 4. Material: Female head and sub-head are made of brass 5. Features: 1) A variety of joints can realize the embedding of various M2 (common to M2.5), M3, M4, M5, M6 (1/4"), and M8 hot melt nuts 2) Compatible with standard 936 universal soldering iron tips, convenient and practical (other models: Hakko FX-888D) 3) The heating press nut hand-tightened knurled joint, the head joint can be disassembled at any time in the cooling state to replace different types of threaded indenter 4) Brass material, good thermal conductivity, end face contact, prevents the nut from skewing, and facilitates quick embedding of the nut into plastic parts 5) Compared with other similar indenter, our indenter is embedded at a small 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 interior of the plastic parts to a certain depth.
