Provides fine adjustment for precise torque delivery with an accuracy of ±6%. Factory-calibrated to meet or exceed the accuracy and repeatability requirements of ISO-6789 and ASME-B107M. Internally adjustable models are available in four torque ranges. Torque is easily adjusted by removing end cap and inserting the Allen wrench provided with each tool. Cam-over torque clutch stops driver when torque applied exceeds limits. Adjustable models, available in three torque ranges, allow operators to quickly "dial-in" torques from end of tool.
