Abstract: An improved anti-theft device includes a fastener covered by a circumferential sleeve intended to slip to prevent torque application directly to the fastener, and a corresponding adapter for connecting a tool, such as a socket wrench, to the fastener. An outer face of the fastener comprises an open abutment wall for engagement by an open actuating wall of the adapter, and at least one locating pin communicates between the fastener and adapter. The invention allows unique configurations of the locating pins and walls for giving the adapter the quality of a key. Torque transmission from the adapter to the fastener is more evenly distributed over a greater surface area as compared with prior art anti-theft fasteners and adapters utilizing pins only for torque transmission.

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.

Abstract: A device for use with a wheel lug nut having a frustoconical exterior surface includes a sleeve-like body adapted to be loosely fitted about the exterior surface of the lug nut so as to substantially cover the exterior surface thereof. The sleeve-like body defines two opposite inner and outer ends and concentrially-arranged, frustoconically-shaped interior and exterior surfaces extending between the inner and outer ends. When operatively positioned about a wheel lug nut used to secure a wheel rim upon a lug stud of a wheel, the sleeve-like body is retained upon the lug nut between the wheel rim and the frustoconical configuration of the lug nut and prevents the lug nut from being tightened or loosened by a tool such as a pipe wrench, operatively clasped about the exterior surface of the sleeve-like body.
