However, the measurements are not too precise. For applications that require specific torque measurements, other torque wrenches have to be used.
The click torque wrench is another variant. Before you use the wrench, you can configure the wrench to use only a specific amount of torque. After reaching the specified torque, the mechanisms slip into place.
