ABSTRACT:
An apparatus particularly useful for securing a deformable nut having a hole to carrier material, such as a sheet-metal panel, is disclosed. Securement of the nut to the panel is made employing essentially a one-step procedure to form a hole in the panel and to secure the nut to the panel at the panel hole. The securement procedure generates essentially no panel-material waste. Various elements of the apparatus cooperate to secure the nut to the panel. On the apparatus, a ram initially causes a nut guide to secure the panel to the apparatus, and eventually causes a piercing punch to be advanced along a path toward a receiving punch. The latter action causes the panel to be pierced. Further advancement of the ram toward a base of the apparatus causes portions of the panel adjacent the pierced portion to be urged or otherwise drawn into the nut hole, and eventually causes the nut to deform. The latter action causes the nut to be secured to the panel.
