Abstract: A magnetic socket wrench assembly includes a tubular wrench body, an annular mounting member, and a plurality of magnets. The wrench body is adapted to be connected to a tool, and has a central hole that includes a shank-receiving narrow hole portion and a socket-defining wide hole portion, which receives the mounting member fixedly and which engages a nut to be rotated on a bolt. The mounting member has a nut-engaging end surface with a plurality of magnet-receiving holes for receiving the magnets fixedly. When engaging the nut, the bolt can extend through the mounting member and into the narrow hole portion.
