  • Patent number: 11845171
    Abstract: An oxygen sensor socket kit provides an air impact driver and at least one slotted socket forming an annulus forming an inside surface with a plurality rectangular flats parallel to and symmetrically arranged around a central axis. The slot is slot formed through the socket sidewall positioned in place of one or a portion of one of the rectangular flats. An outer surface incorporates at least one radially offset protrusion forming a wing body and having a planar striking surface that lies along a radial projection from the central axis on a plane that intersects central axis. A striking surface forms one or more recesses of a concave shape to receive in a rounded tool tip an air impact driver. The driver has an offset distal portion having an angular offset sufficient to allow a direction of an impact force directly laterally offset from a centerline of the output shaft.
