Global 1 Resources offers server rack mounting hardware kits for square and round hole rackmounts. When working with server racks and computer cabinets, cage nuts and server rack screws become crucial. No matter the enclosure you are working with, mounting hardware is needed. There are different types of cagenuts and server rack mounting screws that these cabinets use. The Dell rack typically calls for the 10-32 screws and cage nuts. These are your standard square holse screws. Many of your square hole tabs will work with the 10-32 or the M6 cage nut. Please contact Global 1 Resources with any questions you may have on rack mounting hardware, cage nuts or server rack screws.
