Cage Nuts

A two-part product, a square nut with a spring steel surround. The cage nut consists of a (usually square) nut in a spring steel cage which wraps around the nut.

Cage Nuts

The cage nut has two wings that, when compressed, allows the cage to be inserted into the square holes, in, for example the mounting rails of equipment racks. When the wings are released, they hold the nut in position behind the hole.

The nut is usually slightly loose in the cage to allow for minor adjustments in alignment.
