tening torque will differ according to the di-
ameter of bolt.
• Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class of
bolt and the bolt length.
4. The use of the universal joint or the exten-
sion bar somewhat reduces the fastening force
of the impact wrench. Compensate by fasten-
ing for a longer period of time.
5. The manner of holding the tool or the mate-
rial of driving position to be fastened will af-
fect the torque.
6. Operating the tool at low speed will cause a
reduction in the fastening torque.
