ABSTRACT:
The adapter for the torquing tool includes an elongated body having a bore in at least one end to accommodate a driver bit and a coupling means for detachably attaching the body to the tool. A depth adjustment bushing is threadably engaged within said bore, with the bushing being externally threaded to engage the bore. The bushing includes a body section and a shank section. An axial passageway extends through the shank section and an axial slot extending through the wall of the shank in communication with the passageway. A screw extends through a radial threaded opening in the body and into the axial passageway through the slot so when the driver bit is housed within the body section and extends into the passageway, it is held in place by tightening the screw. In a preferred form, the passageway has a hexagonal cross section for mating engagement with a hexagonal end section of the driving bit.
