the torque tool. The operator then stops applying torque and the desired value on the torque tool is compared with the value displayed on the torque wrench tester. Again the tool may then need adjustment. Torque screwdrivers: For very small torques, below 5 N.m (0.5 Kgf.m) it is common to use a torque screwdriver rather than a torque wrench.
Reset the torque wrench to the final torque value and tighten bolts to full torque using a cross bolt ci rcle sequence. 1. Finger tighten all bolts using the proper torque sequence. 2. Tighten snuggly with a torque wrench set to 1/2 t he required torque, using the proper torque sequence. 3. Tighten to recommended torque range listed on page 4.
