A method of manufacturing rolled pierce nuts having a predetermined profile from a metal rod comprising the steps of:
- a. punching a plurality of through-holes in the rod;
- b. cutting the rod to form a plurality of blank nuts having through-holes using a one out die;
- c. collecting the blank nuts;
- d. tapping a thread into the through-holes of the blank nuts creating tapped nuts;
- e. collecting the tapped nuts;
