    Abstract: The pull stud removal device (10) selectively attaches to a specific model of pull stud (12), which is in turn threadably mounted in a tool holder (14). The removal device (10) has a polygonal-shaped body (20) that includes a top end (22), a bottom end (24), and six outer sidewalls (26) that are configured to form a tool receiving pattern. The top end (22) of the body (20) of the removal device (10) contains a drive socket cavity (28) that is sized and adapted to correspondingly mate with a drive socket (18). The body (20) contains an aperture (30) that penetrates the bottom end (24) and at least one outer sidewall (26). The body (20) of the removal device (10) is sized and configured to laterally slidably receive only a specific model design of pull stud (12). The aperture (30) is circumscribed by a plurality of inner wall surfaces (32) that are correspondingly sized and configured to closely mate with only the particular model of pull stud (12).
