This preset torque wrench with a Gedore Switch Operated Signal confirms that the tightening process has been completed. After each activation, a signal is sent to control production flow or count the completed tightening. The tool is easy to use for operators of any skill level, eliminating the risk of under or over-tightening. It can be integrated into most production lines, and an optional Signal Delay Unit (SDU) is available to help prevent missed wrench activations.
