A fastener temporarily attaches articles through aligned apertures in the articles including a nut plate allowing the articles to be assembled by one assembler. The fastener has a flange, a cylindrical sleeve, and a solid pin. The flange ensures that the fastener does not pass completely through the aligned apertures. The sleeve supports articles and couples with the flange on one end of the sleeve and the solid pin on the other end of the sleeve. The solid pin can support a nut plate and further engages the threads in the nut plate through friction. The juncture between the sleeve and the solid pin is formed to allow the pin to break away from the cylindrical sleeve when pressure is applied. A screw or other threaded fastener is inserted through the cylindrical sleeve and pressed against the solid pin. Once the solid pin breaks away, the threads on the screw engage with the corresponding threads on the nut plate. The flange coupled to the cylindrical sleeve engages with the head of the screw and acts as a washer to prevent the screw from disengaging from the articles. A second flange can be used to further secure the fastener to the articles by passing through one or more of the apertures and springing back to prevent the fastener from slipping out of the apertures.
