applied to the nut or bolt at the right angle.
7. Bit adaptor: Code No. 991476
This is used for tightening small screws (M6 – M8).
NOTE
(1) This adaptor is set only on the anvil (drive angle)
of the main unit. The bit adapter cannot be attached
to the special accessory anvil (square drive).
(2) Before starting work with the adapter, tighten a few
screws with it to make sure it's tightening with the
appropriate torque.
(3) Tightening speed will be greatly reduced when
driving wood, tapping or other similar screws.
