The instructions explain that the thread direction of the screw is positive, while the thread direction of the broken wire extractor is reverse. When the broken wire extractor is turned counterclockwise, it continuously tightens into the inner hole, and the screw rotates when it reaches a certain degree of tightness. Because the screw is turned in the opposite direction, the broken bolt is naturally screwed out. (The 3mm screws may be difficult to operate)

The product is made from Chrome vanadium steel, which provides high hardness, rustproof, and durable construction. The aggressive left-handed (extractors) and right-handed (drill bits) spiral flute design offers extra gripping power. This damaged Screw Extractor Set is neatly contained inside a heavy-duty plastic blow-molded case for convenience.

The drill bits' diameters and recommended extract diameters of broken screws are etched on the case. This set is ideal for removing damaged, rusted, or stripped screws, studs, bolts, fasteners, metal water taps, and water tubes. To use, first drill a hole on the broken screw with an electric drill, then gently tap the extractor into the hole and use a wrench to rotate counterclockwise to take it out.
