Abstract: The present invention is a modification of U.S. Pat. No. 9,416,601 that is incorporated herein as if fully set forth. Once the tool is secure to the tubular, axial translation of the driving nut to the “locked” position prevents selective grip or release. A slot cut in the driven nut and in the surrounding housing allows additional right hand rotation so that a lug is captured on a shoulder to prevent subsequent axial compression of the selective grip assembly, where the tubular grip will be maintained with rotation. By preventing the tool from moving to the “unlocked” position when set down weight from the rig as applied, it can be operated in a variety of common conditions in today's well drilling environments with applied tension or compression as well as rotation in a direction that leaves the lug captured on a ledge adjacent the slot cut in the driven nut.
