Captive 'U' nuts/clips provide a simple solution to the problem of using a machine or self-tapping screws in otherwise unsuitable thin sheet materials, such as sheet metal, fibreboard, hardboard, etc. Captive Nuts are also known as Cage Nuts or Clips Nuts and they are multiple-threaded fasteners used usually on many thin materials. They are mostly square nuts in a spring steel cage that wraps around the nut. The cage is built of 2 wings that when compressed allow the cage to be inserted into the mounting hole and when released, secure, lock, and hold the nut in the desired position.
