A stud bolt tool and method for using the stud bolt tool to install or remove a threaded stud bolt from a threaded blind bore. The stud bolt tool has a cylindrical housing having a first and second surface and an internally threaded bore communicating with the first and second surfaces. The housing includes a plurality of circumferentially spaced ports surrounding the internally threaded bore. The ports communicate with the first and second surfaces of the cylindrical housing and each port has a threaded portion extending to the second surface. A plurality of balls are slidably stacked in each port. The ball nearest the first surface is capable of partially protruding beyond the first surface and is also capable of retracting within the port below the first housing surface. A screw threadably engages each threaded portion of each port. Advancement of the screw into the port forces the ball to partially protrude beyond the first surface.
