The captive nut that is used in server racks that is a bitch to install without the proper tool. Sometimes a screwdriver is used in lieu of the special tool. Using a screwdriver can lead to injury when the screwdriver slips off and stabs the hand securing the bitch nut.

Also a bitch because they are never supplied with equipment and are often forgotten when equipment is ordered.

Origin: A cage nut or caged nut consists of a square nut in a spring steel cage which wraps around the nut. The cage has two wings that when compressed allow the cage to be inserted into the square holes in equipment-server racks.
I need a box of bitch nuts for the new server that is to be installed in the server rack.
