Claim:
A method for installing an anchor bolt, the method comprising: providing a rotary hammer having a first mode consisting of axial hammering, a second mode consisting of rotation, and a third mode consisting of axial hammering and rotation; mounting to a chuck of the rotary hammer an adapter fitting comprising an elongate shaft terminating at a distal end with a socket square drive fitting and terminating at a proximal end in a cylindrical portion having recesses arranged for receiving protrusions projecting from the chuck of the rotary hammer to couple the cylindrical portion with the chuck so as to mount the adapter fitting to the chuck of the rotary hammer; selecting an interchangeable drive socket that has at a distal end a polygonal-shaped opening that corresponds to a size and shape of a head of the anchor bolt, the interchangeable drive socket also having at a proximal end a square opening that corresponds to a size and shape of the socket square drive fitting; mounting the interchangeable drive socket to the adapter fitting by engaging the socket square drive fitting with the square opening; engaging the anchor bolt with the drive socket by engaging the polygonal-shaped opening with the head of the anchor bolt; driving the anchor bolt into a mounting hole by driving the adapter fitting and the drive socket with the rotary hammer operating in axial hammering of the first mode or the third mode; and rotating the adapter fitting and the drive socket with the rotary hammer operating in rotation of the second mode or the third mode so as to secure the anchor bolt within the mounting hole.
