The material is too thin to machine the thread. It requires a tool or device to install in seconds from one side of the work. The added benefit of not only being a dependable fastener, but they are also ready to use with clean threads available for screw attachments. Blind Rivet Nuts also are used when an application has little or no access to the backside as they can be installed from the front side of the workpiece.
