ABSTRACT:
A pierce nut installation apparatus having a feed passage, a plunger passage and a plunger which reciprocates through the plunger passage to engage and install a pierce nut in a panel opposite the plunger passage, wherein the end of the plunger passage includes a nut guide element projecting from the end of the plunger including a frustoconical outer surface having a major diameter adjacent the end face of the plunger substantially equal to the crest diameter of the pierce nut bore which accurately locates the pierce nut on a panel and prevents cocking of the pierce nut in the plunger passage.
