Abstract
For tightening or loosening a threaded connector which has a part to be turned with a plurality of engaging formations, a power tool is utilized in which at least two pawls engage the engaging formations and are displaced to turn the part which is to be turned, and at the same time the pawls are arranged so that a distance between the pawls is smaller than the distance between the engaging formations so as to reduce a power stroke of the drive of the power tool.
