The present invention relates to a trapezoidal nut made of sheet metal, proportionally folded under a bend angle to form two parts, with a threaded hole and spikes on one side and a smooth surface hole on another side. The purpose of the invention is to add the ability to attach any object to a nut without compromising its integrity and general purpose, and reliably use a nut without spontaneous unscrewing and detachment from the mounting plane. The goal is achieved by the fact that the trapezoidal nut is fastened with a use of a threaded hole and fixed to be in a static position, with the help of spikes. The smooth surface hole can be used for any purpose at the discretion of the user. The result of the work of the trapezoidal nut is a reliable fixation (without unwanted unscrewing) on a flat surface and the ability to tie or hock anything or any means attached to it.

An over-the-door hanging apparatus includes a mirror apparatus including a frame and a mirror mounted thereto, and first and second elongate bracket members. The mirror apparatus further includes first and second mounting structures coupled to the frame. The first and second elongate bracket members each include a bracket and a mounting element. The mounting elements of the first and second bracket members are configured to be engaged with the first and second mounting structures of the mirror apparatus. The brackets of the first and second elongate bracket members are configured to engage a top edge of a door to hang the mirror apparatus from the door. As such, the mirror apparatus can be hung from the door in a tools free manner.

An over-the-door hanging apparatus includes a mirror apparatus including a rear surface and a top edge, a first mounting element located on the rear surface of the mirror apparatus, and a first elongate member having a first bracket for engaging a top edge of a door and a plurality of second mounting elements. The first elongate member is configured to be mounted to the mirror apparatus at a first position by engaging a first one of the plurality of second mounting elements of the first elongate member with the first mounting element on the rear surface of the mirror apparatus and at a second position by engaging a second one of the plurality of second mounting elements of the first elongate member with the first mounting element on the rear surface of the mirror apparatus. The first and second positions correspond to different hanging heights for the mirror apparatus.
