Abstract: A fastener installation tool which includes an axial assist mechanism as well as adjustable feet and a simple drive position limiter. The installation tool is connectable to the chuck of a standard drill. During use, the feet are stepped upon, causing the housing to move along the drive shaft, generally toward the fastener, causing the feet to contact the workpiece. Then, the drill is actuated, causing the drive shaft to rotate and the fastener to thread into the workpiece. At some point during fastener installation, further axial motion of the tool stops as the fastener continues to travel axially due to threading action, and reduces its head engagement with the drive socket. As the fastener seats on the workpiece, the drive socket disengages from the head of the fastener.
