Patent ID: 8523504

Claim:
A license plate security device, comprising: a spin barrel assembly generally in the form of a hollow cylinder with a closed bottom and an open top; a hole sized to accommodate a machine screw with a head in said closed bottom of the spin barrel; and a transverse hole on the side of the cylinder to accommodate a security set screw; and a machined slug with a transverse threaded hole to accommodate a security set screw is sized to fit completely inside said open end of the spin barrel to rest on a lip inside of the spin barrel wherein the security set screw secures in place the machined slug; wherein the removal of a license plate secured by the license plate security device thereafter requires a security tool to remove the security set screw to remove the machined slug from the spin barrel to access the head of the machine screw, and wherein turning the spin barrel only creates a slip joint that will not transmit enough torque to remove the machine screw.
