Stahlwille 730/40 Torque Wrench 80-400Nm

Stahlwille 730/40 Torque Wrench

Built for daily workshop use, the 730/40 combines speed, accuracy, and ergonomics. The clamping lever enables quick flash setting to the required torque, while the mechanism only loads the measuring element during the tightening process, removing the need to back off to 0 between jobs. An ergonomically shaped, non-slip adjustment element with a thumb recess and an optimised ball handle helps reduce strain over long shifts. When the target torque is reached, a clear tactile and audible double stop signal confirms completion. The square receptacle takes exchangeable plug-in tools for flexibility across fastener types, and left-hand tightening is achieved by turning over the plug-in tool.
