Abstract

A nut installation apparatus or head for installing self-attaching nuts, such as pierce nuts, in a panel, without the requirement of a large forming die press assembly. The apparatus includes a nut anchor, which holds the first or end nut stationary, a relatively movable die member, opposite the nut anchor, which supports the panel and a resiliently supported nut guide having a passage receiving nuts in bulk or strip form. The panel is biased into contact with the end nut and nut guide, by the movable die, to install the nut in a panel. Where the nuts are in strip form, the apparatus first severs the end nut from the strip and then attaches the nut in the panel, in a separate step. A unique sensor is provided to assure proper installation.
