ABSTRACT:
A two-piece kit facilitating the removal of a damaged wheel lug stud from a wheel hub or the like includes a ribbed nut having a splined through-aperture extending between the faces of the nut and drive-on tool defining an axially-extending recess in one of its ends for loosely accepting the nut when the nut is placed endwise within the tool recess. The through-aperture of the nut defines a plurality of radially inwardly-projecting edges extending axially along the nut and is of such size to grip the cylindrical periphery of the lug stud and thereby prevent relative rotation between the stud and the nut body when the nut is operatively driven upon the stud so that the through-aperture encircles the cylindrical periphery of the stud. When the nut body is placed endwise into the tool recess and operatively driven upon the wheel lug stud as aforesaid as the drive-on tool acts as an intermediary member between the nut body and a driving tool, the drive-on tool can be removed from the nut body and the lug stud unscrewed as the nut body is manipulated with a conventional socket wrench. The method of the invention includes the steps involved in using the kit of this invention to remove a damaged lug stud and the drive-on tool to salvage the ribbed nut for reuse.
