Abstract
An anchor for a bolt formed of a single strip of sheet metal includes a pair of opposed shell portions having helically aligned connecting strips. The shell portions extend from a bottom end of the anchor having a threaded sleeve for accepting the bolt. The free ends of the shell portions have tabs extending outwardly for engagement into the plate in which the member is being installed. The anchor is formed by first stamping a strip of metal and then bending the ends of the strip to form a cylindrical shell. Axially aligned tabs on the free ends extend into complimentary recesses to join the two shell halves together.
