Instructions:
1. The thread direction of the screw is positive, while the thread direction of the broken wire extractor is reverse.
2. When the broken wire extractor is turned counterclockwise, it is continuously tightened into the inner hole, and the screw rotates when it reaches a certain degree of tightness.
3. Because the screw is turned in the opposite direction, the broken bolt is naturally screwed out.(The 3mm screws may be difficult to operate)
Please read the description clearly.
