This captive nut from RS PRO is designed to fasten soft-metal sheeting. It eliminates the need for threaded screws that could damage the finish of thin materials. You'll find fasteners like this used in both industrial and electronic applications.
The component's zinc-plating acts as barrier protecting the inner metal, preventing moisture from affecting the nut and stopping it from tarnishing, for a longer-lasting product. Its steel-spring cage has a passivated coating for high resistance to chemicals and corrosion, again improving its service life. This versatile nut is suitable to use on a wide variety of panels ranging in thickness from 0.5 mm to 1.6 mm.
A fastener like this is commonly used to secure the rails of equipment racks. It's also a convenient solution for mounting equipment in blind locations as you don't need a drill to fix it in place.
