A cage nut is also known as a captive nut it inheres of a commonly square nut in a spring steel cage that wraps around the nut. The cage consists of two wings that when compressed allow the cage to be inserted into the square holes, for example, in the mounting rails of equipment racks. When the wings are released, they hold the nut in position behind the hole. HELLARY offers three main types of cage nuts that vary according to their size 10-32, 12-24, and M6.
