50-Pack Black M6 Cage Nuts and Screws for 19-inch Racks

The M6-C50B is a 50-piece mounting hardware set designed for installing equipment and accessories in compatible 19-inch racks and network cabinets. It includes black M6 cage nuts and matching screws for securing switches, patch panels, shelves, cable-management panels, power distribution units, and other rack-mounted components to square-hole mounting rails. The cage nuts are inserted into the rack rail from the rear and provide a threaded fixing point for the screws. This makes the set suitable for new installations, equipment replacements, rack expansion, and routine maintenance. The black finish helps the fasteners blend neatly with dark rack enclosures and installed hardware. Before installation, the rack rail hole type, screw size, and mounting requirements of the equipment should be checked to ensure compatibility.
