Case 3614 ABSTRACT A driver bit attachment for a power tool for preventing over-torquing of the fastener. A driver bit is received in a first bore and a second larger bore of a cylindrical attach- ment body. A projection permits attachment to a drill or screw gun. The projection has a tapped recess extending axially therein which receives a set screw. The end of the set screw engages the trailing end of the driver bit to position it within the two bores and, thereby, determine the point at which the fastener will disengage itself from drive by pulling itself out of contact with the driver bit. -1-
