PRODUCT DETAILS:

This cage nut is comprised of a spring steel cage which wraps around a square nut. The cage has two wings that compress to allow the cage to be inserted into a square hole punched in an equipment assembly or sheet metal.

When the wings are released they hold the nut in position behind the hole. The square nut fits loosely within the cage to allow for slight alignment adjustments.

CAGE NUTS or CAPTIVE NUTS are self-retaining as they slide into bolt-receiving position at panel edges or centered-panel locations. CAGE NUT bolt retainers are ideal for application requiring high torque and extra holding power.

Also known as a caged nut, captive nut or clip nut.
