In some instances, network equipment can be damaged during installation due to improper installation hardware be used on the equipment. For example, screws that are of an incorrect length (in particular, longer than prescribed in installation manuals) can sometimes damage a printed circuit board assembly (PCBA) or component of the equipment. Techniques are presented herein that introduce a foolproof design concept for converting a through hole to blind hole clinch nut for a rackmount bracket. A first aspect of the presented techniques encompasses adding a threaded protection cover to a clinch nut to prevent the excess protrusion of a screw. A second aspect of the presented techniques encompasses a customized blind clinch nut that can restrict (through, for example, a metal plate) the travel of a screw. A third aspect of the presented techniques encompasses adding a press fit metal cap that can restrict travel of a screw. A fourth aspect of the presented techniques encompasses a fastener having a swaged rim feature. Use of the presented techniques can help to reduce the number of products that are returned due to potential installation issues.
