ABSTRACT:
A frame assembly and method of making includes forming a series of pairs of aligned, inwardly extending markings in the form of detents or holes at selected positions in opposed track side walls preferably before forming the sheet metal into the U-shaped profile, providing aligned holes at selected positions in end portions of each stud, inserting the end portion of the stud inside a track so each marking is in an adjacent hole of the aligned pairs of holes and markings, and punching through the markings into each hole to form a hollow stem that draws the end of the stud into the track and the end of the stud against the top surface of the base wall of the track, brings the centers of the holes and markings in alignment to positively fasten each stud to each track. A further step may include flaring or flattening the open end of the stem to a selected angle to form a rivet head.
