Blind Rivet Nuts are used primarily to install threads in sheet or platemetal where a drilled and tapped thread is not an option.
Blind Rivet Nuts also have an advantage over other captivated fasteners because they can be installed on site after a component has been assembled. They can also be used for repair work to replace a previously installed fastener that has failed. The fact that they offer blind installation means that you don't have to have access to the back of the panel.
