Thefasteningtorqueisaffectedbyawidevarietyof
factorsincludingthefollowing.Afterfastening,always
check the torque with a torque wrench.
1. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
2. Driver bit or socket bit
Failuretousethecorrectsizedriverbitorsocket
bit will cause a reduction in the fastening torque.
3. Bolt
• Eventhoughthetorquecoefcientandthe
class of bolt are the same, the proper fasten-
ing torque will differ according to the diame-
ter of bolt.
• Eventhoughthediametersofboltsarethe
same, the proper fastening torque will differ
accordingtothetorquecoefcient,theclass
of bolt and the bolt length.
4. Themannerofholdingthetoolorthematerial
of driving position to be fastened will affect the
torque.
5. Operating the tool at low speed will cause a reduc-
tion in the fastening torque.
