The pull stud removal device ( ) selectively attaches to a specific model of pull stud ( ), which is in turn threadably mounted in a tool holder ( ). The removal device ( ) has a polygonal-shaped body ( ) that includes a top end ( ), a bottom end ( ), and six outer sidewalls ( ) that are configured to form a tool receiving pattern. The top end ( ) of the body ( ) of the removal device ( ) contains a drive socket cavity ( ) that is sized and adapted to correspondingly mate with a drive socket ( ). The body ( ) contains an aperture ( ) that penetrates the bottom end ( ) and at least one outer sidewall ( ). The body ( ) of the removal device ( ) is sized and configured to laterally slidably receive only a specific model design of pull stud ( ). The aperture ( ) is circumscribed by a plurality of inner wall surfaces ( ) that are correspondingly sized and configured to closely mate with only the particular model of pull stud ( ). The receival of a pull stud ( ) into the aperture ( ) of the removal device ( ) results in a portion of the majority of the inner wall surfaces ( ) of the aperture ( ) mating with a substantially large region of the outer surface area of a pull stud ( ), thereby significantly increasing the level of torque that may be applied to a pull stud through a drive socket ( ) mounted in the drive socket cavity ( ) of the removal socket ( ), for tightening and removing a pull stud ( ) from a tool holder ( ).
