Our automatic shut-off nutrunners are designed for automated assembly applications involving materials such as plastics, glass, or metals that require spot on torque accuracy. This line of tools excels in the field when fastening hard or soft joints, and provided the tapping torque does not surpass the final torque, the driver can also be utilized for self-tapping screws. All of our nutrunner models feature forward and reverse modes, and come with a 30 day satisfaction guarantee as well as a 1-year warranty.
