ABSTRACT:
A conventional set of dual wheels having rims with tires thereon are effectively locked on a wheel hub mounted on the end of an axle on a trailer chassis by replacing two of the studs and hexagonal nuts, normally provided for holding the dual wheels on the wheel hub, with security bolts. When the threaded ends of the security bolts are engaged on the wheel hub, their cylindrical heads are of such a size as to substantially abut the underside of the cylindrical surface of the rim of the outer wheel of the set of dual wheels. Each security bolt has a square opening provided on the end of the cylindrical head thereof to receive the square projection on the end of an adaptor provided for a wrench which is also used for tightening and loosening the hexagonal nuts. Such a structural arrangement makes it difficult, if not impossible, to loosen the security bolts as needed to remove the wheels from the wheel hub while the trailer is parked at a terminal.
