Specification Brand : Hilitand BulletPoint1 : 936 UNIVERSAL SOLDERING IRON TIPS: Soldering tips are interchangeable with standard 936 general purpose soldering iron tips for use with M2 (M2.5 common), M3, M4, M5, M6 (1/4 inch), M8 and other hot nuts or inserts. BulletPoint2 : PRACTICAL CHANGE SYSTEM: Due to the thread in the soldering iron adapter, the soldering tips can be changed very easily WITHOUT completely unscrewing the soldering iron. BulletPoint3 : BRASS MATERIAL: Heat set inserts are made of brass for better thermal conductivity and face to face to prevent nut skewing and facilitate quick insertion of nuts into plastic parts. BulletPoint4 : EASY TO USE: The small distance embedded in the pressed head avoids the plastic parts, so the head is not easily damaged to the plastic parts, and can be inserted into the plastic parts to a certain depth. BulletPoint5 : 3D PRINTER PARTS: 3D printer soldering tips are commonly used for 3D printers to print parts with hot copper nuts or to implant nuts on plastic.
