ABSTRACT:
A lockout device for restricting access to a nut through which a stud passes in threaded engagement with the nut comprises a cylindrical cap and a corresponding adapter. The cap includes first and second opposite ends and has a hollow portion opening through the first end of sufficient size for receiving most or all of the nut. A threaded hole sized for threaded engagement with the stud extends in an axial direction through the second end of the cap to communicate with the cap's hollow portion. The adapter includes a leading end and a trailing end, and has a hexagonal configuration adjacent its trailing end and an axially extending stud hole through its leading end sized to accommodate the stud. The second end of the cap and the leading end of the adapter are configured for end-to-end coupling with one another, such as by providing pin holes and corresponding pins, to enable torque to be transmitted from the adapter to the cap while the cap is in threaded engagement with the stud. The invention has utility for preventing theft of heavy duty truck and vehicle wheels.
