5pc single head high speed steel screw extractor

The thread direction of the broken wire extractor and the direction of the general screw thread are reversed. When the counterclockwise rotation is performed, the broken wire extractor is continuously tightened inside the inner hole, and the screw rotates after reaching a certain tightness, because it is reverse Turning the screw in the direction will naturally turn out.

Instructions:

First, choose a broken wire extractor that is thinner than the screw that is torn, and then find a drill of the same size as the thinnest end of the broken wire extractor and drill a hole deep enough in the middle of the broken screw. Then screw the threaded screw counterclockwise into the screw to be screwed until the screw is unscrewed.
