This is a set of extractors for damaged screws, bolts, and pipes. It can remove screws and pipes that are damaged, rusted, or seized and cannot be removed with ordinary tools.
It comes in 8 sizes and works not only with wood screws and machine screws, but also with flat-head screws, hex screws, and paint-over screws. It can remove some common screwdriver parts, but cannot disassemble damaged bolts, screws, bolts, or pipes. The reverse thread bit easily removes screws, bolts, studs, and threaded pipe fittings.
Made from high-quality carbon steel, it offers excellent hardness and durability.
