Innovation (100 Pack) M6 16mm Long Screws & Cagenuts - Cage Nut, Screw - 0.63" - Gold - 100 Pack

A cage nut is a square nut that has threaded holes wrapped in a piece of spring steel designed like a cage. You would use a cage nut when you have a rack that has square mounting holes and you need to mount a product that requires a threaded hole.

The spring steel on the cage nut has two flanges that when pressed together, allow the cage nut to be inserted into the square hole and clip in. The cage nut is typically loose in the cage to allow for adjustments when installing the screw.

There are 3 common sizes for cage nuts: 10-32, 12-24, and M6. You can determine what size you need by the product you are mounting. For an easier instillation, we recommend you purchase the corresponding screw to use with the cage nut."
