Abstract
An anti-tampering device secures bolted components, such as a trailer coupler mounted to an adjustable channel. A nut shield provides hexagonal channels in which nuts are contained. A hasp assembly provides a locking tab. Bolts secure the nut shield and the hasp assembly to the components. A hasp shield with a notched annular flange overlays the hasp assembly, receives the tab through a slot in the area surrounded by the notched annular flange, and contains a puck lock in the area. The puck lock engages the locking tab.
