Specification Brand : Focket BulletPoint1 : 【HIGH QUALITY BRASS MATERIAL】This heat set inserts are made of brass for better heat conductivity, and the face-to-face prevents the nut from skewing and makes it easy to quickly insert the nut into plastic parts. BulletPoint2 : 【MULTIPLE SIZES AVAILABLE】This heat set insert tool is interchangeable with the standard 936 Universal Soldering Iron Tip for use with M2 (M2.5 Universal), M3, M4, M5, M6 (1/4 inch), M8 and other heat set nuts or inserts. The meticulously crafted tips are smooth with perfectly rounded edges for smooth sliding between the tip and the brass insert. BulletPoint3 : 【EASY TO REPLACE】This m3 threaded insert is threaded, making it very easy to change soldering tips without having to completely unscrew the soldering iron. The indenter is inserted at a small distance, avoiding the plastic part, so the indenter is less likely to damage the plastic part and can be inserted to a certain depth into the plastic part. BulletPoint4 : 【FOR 3D PRINTING】The soldering tools are easily accessible to 3D printer parts without touching the soldering iron and melting the plastic, and are designed for mounting thermoset inserts in 3D printed parts. To maintain the performance of the thermoset insert, keep it in a dry and clean environment when not in use. BulletPoint5 : 【100% SATISFACTION GUARANTEE】We are committed to making every customer satisfied, if you have any questions during the purchase process, please feel to us.
