Abstract

An improved installation apparatus and method of attaching a female fastener element, such as a self-riveting nut fastener, to a metal panel, wherein a small hole is first formed in the panel and the annular riveting portion of the fastener is driven through the hole and locked to the panel. The improved method of this invention includes locating the fastener on the panel, then driving a tapered punch through the fastener board to pierce a small hole in the panel, then driving a conical exterior surface of the punch through the hole, to enlarge the hole, and substantially simultaneously driving the fastener riveting portion against the panel and through the panel opening into a die member to lock the fastener on the panel.
