General information

Turn your bits and a holder into your perfect torque tool. Conveniently combinable with preset torque for tightening or loosening. These high-precision precision tools are available from 0.2 to 0.5 Nm and are used in combination with 1/4 inch bits. Often used as a complete solution for work on electronic devices, in quick-change systems, robot stations, aerospace, medical technology, or simply on any workbench where precise torque is required. The clicking sound indicates when the torque has been reached, so that the adapter cannot be overtightened. When loosening screws, there is no torque release (due to the locked core shaft), so no additional loosening tool is required.
