A stud installer is provided that will not transmit torque to the spindle while the stud is being installed. Additionally, the stud installer of the present invention will not transmit force in a direction perpendicular to the stud. The present invention includes a collar (20) having a longitudinal bore therethrough. The collar has a bearing surface (24) at one end and support surface (22) at the other. The collar can be of various geometries such as a straight cylinder or cylindrical with the support surface of larger diameter than the bearing surface. A stud puller (40) of unitary construction is also provided which includes an upper portion (43) and a lower portion (50). The lower portion is constructed to be received by the bore in the collar. The upper portion (43) has a diameter greater than that of the bore (26) of the collar. In this manner, the upper portion rests on the collar and is free to rotate about the central longitudinal axis of the collar. If desired, a washer (30) can be placed between the upper portion of the stud puller and the collar to allow the stud puller to rotate with a minimum of friction. The stud puller includes a threaded bore therethrough with threads corresponding to those of the stud to be installed. The bore extends completely through the stud puller so that the stud puller may accommodate studs of any length. |
