Abstract: An adapter tool device for transmitting rotary energy by means of special internal driving end splines to create and cut gripping channels in threaded and unthreaded cylindrical objects adapted to fit drive end shapes of rotary power sources and transfer torque from reversible and non-reversible variable speed rotary torque power sources such as impact wrenches, impact drivers and hand wrenches for in-line coincident centerlines as well as for non-coincident angularly disposed centerlines whereby rotary power is transferred to tighten or loosen cylindrical fastening components such as bolts, screws, combination nut-bolts, threaded components, non-threaded cylindrical components and the like.
