ABSTRACT:
A bolted fastener for joining components, such as a bracket fastened to a crosspiece, includes a bolt, a nut and an eccentric. A square neck of a bolt fits into an oblong hole in a component and prevents the bolt from turning. The diameter of the eccentric that serves as a wedging means fits into the slightly larger diameter of the receptacle hole, allowing the eccentric to fit into the receptacle hole. When the nut is screwed on the bolt, the eccentric rotates about the bolt and, on account of its eccentricity, wedges itself within the receptacle hole. The wedged eccentric prevents accidental loosening or accidental unscrewing of the nut.
