that mates flushly with a wheel hub to allow the outer cylinder 11 and inner cylinder 12 to rotate freely thereabout the ability of the outer cylinder 11 and inner cylinder 12 to rotate makes grasping the two extremely difficult with a tool which prevents adequate engagement of a cutting tool onto the cylinder surface without inducing rotation of the cylinders the rotation prevents the cutting tools from being utilized to their potential as the motion of the tool creates rigid body rotation of the cylinders as opposed to removing material therefrom to expose the outside surface of the locking nut 13 in addition outer cylinder 11 and inner cylinder 12 are preferably made of stainless steel which prevents removal with an acetylene cutting torch stainless steel contains high levels of chromium and nickel which are stable at high temperatures and prevent the torch from burning through to the iron in the steel during operation the outer cylinder 11 and inner cylinder 12 are also longer than the locking lug nut 13 which prevents the use of a reverse thread tools which could otherwise remove the locking lug nut 13 using a reverse tapping method or outward engagement of the locking nut to bypass the specialty key combined these design aspects afford a significantly higher amount of protection than the prior art meaning the present invention will not be easily defeated by many of the common tools used to steal trailers such as bolt cutters power saws cutting torches and specialty lock removal tools the lug nut key 14 comprises a specific geometry that requires a conjugate key to engage with the locking lug.
